Question From ronalds1 on 2003 pontiac sunfire misfiring

I HAVE A 2003 PONTIAC SUNFIRE WITH OVER 100,000 MILES ON 2.2 OHC MOTOR WAS RUNNING FINE YESTERDAY MORNING WHEN DROVE IT THEN DAUGHTER DROVE TO STORE WHILE RAINING HARD AND WENT THRU HEAVY PUDDLES THOUGHT MIGHT BE WATER ISSUE BUT SOUNDS LIKE IS ONLY FIRING ON 2 CYL INSTEAD OF 4 AND EXHAUST ONLY COMING FROM ONE TAIL PIPE DONT KNOW IF IS RELEVANT BUT TOOK TO AUTOZONE AND THEY GOT CODE THAT IT HAS MULTIPLE MISFIRES REPLACED SPARK PLUGS AS THEY SUGGESTED BUT DIDNT HELP WHAT ELSE COULD IT BE?

Response From Sidom Top Rated Answer

This system uses a type of waste spark system basically 1 coil fires 2 cylinders..... the pairs are 1&4, 2&3. So if the codes you got were P0301 & P0304 or P0302 & P0303 that would indicate one of the coils isn't firing. unfortunately you can't swap coils on this one to see if the problem moves...

Considering what happened I would probably be looking a connectors for signs of water, maybe taking some apart to see if there is any water in any of them.......... I suppose its possible for one side to go out but it sure seems coincidental considering what happened.......

By the way.... What codes did you get?

Response From Guest

sidom thank you for the suggestions the code is p0300

1998 Pontiac Sunfire GT overheating

Question From Oshawaguy20 on 1998 Pontiac Sunfire GT overheating

Hey, I have a 1998 pontiac sunfire GT 2.4L.

Currently the car will let me drive it for about 20 mins and then the temp gauge begins to rise.. it gets about 6/8th of the way up on the gauge (still technically in a safe zone) and my coolent starts leaking out of the overflow.
The rad fan was not functioning, so I went and replaced the entire rad fan, and it works fine.. But the car is still overheating and the coolent gets so hot, that it starts to boil and leak out of the overflow.. What should I do? I think it could possibly be the water pump, but there is no grinding or whining noise that would indicate the pump dying out.. I'm at a loss and not sure what to do.. PLease help!

Response From Hammer Time

You could still have air in the system from previous overheating or you could have more serious problems with a head gasket for the same reason.

Response From Oshawaguy20 Top Rated Answer

I dont think it is the head gasket, due to the fact that I am not spewing out any white smoke ( or any smoke) out the tail pipe. The water pump seems to be okay as well, I cant hear any grinding or whining noises coming from the engine that would indicate this. I think my next step is to install a new thermostat. WOuld anyone have the process on how to change a thermostat in a 2.4L engine? and if so can you please post how to do it? Thanks alot, hope to see a response by morning so I can do it before I work.

Response From Hammer Time

You seem to think you have it all figured out so good luck with that.

Response From Oshawaguy20

Oh, I'm sorry.. I seem to have thought that this forum was supposed to provide assistance with technical car issues, not sarcastic responses to what I 'think' may be wrong. I was simply asking for an opinion, and possible solutions based on what was going on with my car. Thanks.

Response From Hammer Time

I seem to have thought that this forum was supposed to provide assistance with technical car issues,

That's correct. We volunteer our time and experience to help people with advice which I did, and your response was that I was wrong and decided to go in an entirely different direction which was never suggested and only serves to waste my time.
I've helped thousands of people here but I'll be the first to admit, I have no patience with people that want to debate the advice I give them with their years of shadetree knowledge.

You'll be in for a surprise when you go to replace the thermostat on that engine, if you can even find it. There are ways to find out if a thermostat is working properly or not.

Response From Oshawaguy20

And you fail to remember this is the internet where people for 1 are not always trustworthy. For one, I am not trying to debate the issue, I was simply saying why I thought it was the thermostat.. Maybe if you explained a little why you thought it was the head gasket, or explained why it wouldnt be the thermostat instead of "losing your patience" maybe you should have a little more patience with people on here, because obviously if one is posting asking for help, obviously they wont know as much as you.. Its like calling a tech support centre for your internet.. they wont get angry at the customer because they ask questions based off their knowledge. Don't get offended because I asked a question / tried to make my own diagnoses. I am not calling anyones intelligence or knowledge into question, I just want to fix my damn car. So, if you do in fact think it would be the head gasket, can you please explain to me why - as I don't know how or why it could be the gasket. Thank you

Response From Hammer Time

Head gaskets can fail in many different ways and actually only blow white smoke in the most severe situations. Most times they are just allowing compression to leak into the cooling system and burning small amounts of coolant. The compression in the cooling system will both create air pockets and superheat the coolant. If you read back, that was one of 2 suggestions I made that need to be at least looked into. Believe me, you don't want to change a thermostat on this engine unless you have to and it's not acting like a stuck thermostat. Make absolutely sure the system is full of coolant (not water) and the fans come on at around 225degrees before moving onto anything else. You can tell when the thermostat opens by feeling the temp of the lower hose and when you feel it suddenly get hot, the thermostat has just opened which should happen around 200 degrees.

Response From Oshawaguy20

Okay, so is 50/50 premixed coolent no good? and how much would I be looking at in repairs if you are correct in it being the head gasket?

Response From Hammer Time

50/50 is preferred. Head gaskets can run $800 or $1000, depending on the extent of damage but don't get ahead of yourself. Find out for sure what is going on.

Response From Oshawaguy20

Okay cause I have been using 50/50 I'll go look into this and check back when I get some more information. thanks for the advice. It's appreciated.

Kyle.

Response From Mr.scotty

There is many ways a headgasket can blow.
It could be combustion gases getting into the cooling system causing it to over heat (I had this same problem with a car i fixed for my sister).

If you don't like Hammer times suggestions then buy a repair manual and figure it out your self.., This man has been doing this a long time and knows what he's talking about.
And it's hard to give you a perfect solution without seeing the car in person.

Response From Oshawaguy20

I'm not looking for a perfect solution, just possible issues due to what symptoms the car is showing. Im no expert, I just know some of the tell signs the car may show for some issues and thanks for the advice, after I replace the thermostat if the issue keeps happening I'll probably have to take the car to my garage to check out the head gasket. Thanks!

Rough start - Black smoke

Showing 2 out of 2 Posts
Question From worzip on Rough start - Black smoke

Hi,

My 2000 Pontiac Firebird has started rough since I bought it a year ago. The starter does not have problems, it turns just fine. The engine will just chug and sometimes start rough or sometimes it will fail and I'll have to try again. (It always starts after a few tries at most) Some additional info

- It does not start rough all the time. Sometimes, it has no problems at all.

- Only seems to happen on a "cold" start... If I get the car started and turn it off and do it again and again, it will start fine each additional time.

- The car seems to struggle until it gets some gas. Once I pump the gas a bit, problem solved.

- When it has this problem, black/gray smoke comes out the tail pipe

A friend of mine suggested that I clean the throttle body. He helped me do this and it didn't help.

Any ideas?

Thanks

Response From Tom Greenleaf Top Rated Answer

Sounds like a fuel injector leakdown problem. It's behaving like flooded because it probably is. Pumping the gas doesn't really pump gas in it just increases air flow which is sensed and would add fuel accordingly as needed but wouldn't do anything if engine was off.

Cleaning throttle body may help but I don't think that's it. Try just putting the key to run position for several seconds before you go to start it and see if it behaves better or clears out faster. That black smoke is unburned fuel and not good for your converters so fixing this may save you some bucks,

Coolant overflowing from rad with engine off and cold

Question From highmfer on Coolant overflowing from rad with engine off and cold

Year 2003
Make Pontiac
Model Montana
Engine size 3.4
Mileage/Kilometers 225 000km

To start at the beginning: started losing cabin heat, intermittent heat(cool on idle, warm while driving) Water pump and t-stat were replaced with new parts. System was filled and bled.(bleeding done three times to ensure straight coolant flow from bleeders). Van does not overheat, take to long to reach op temp, blow white smoke from tail pipe, no oil in coolant or vise-versa. Fans come on and work properly. but still no cabin heat.
Now the really puzzling part: when i removed the rad cap to check level of coolant, coolant poured out of the filler. Engine was COLD and NOT running. Front end was jacked up so rad was highest point. I then squeezed the lower rad hose to look for bubbles, none. I squeezed the hose until level in rad was low enough to see top of rad fins, waited a sec and the level began to rise again to the point it overflowed again. At this time the overflow reservoir was empty, so it wasn't refilling from that. I'm really stumped here, any help would be appreciated!

Response From highmfer

Ok...so today I installed the AC Delco T-stat and sorted out that. I refilled the system after a quick water flush, basically just the rad. Filled until the level remained to the filler neck with out dropping or bubbling. Also side note, I opened both bleeders while filling and left them open until coolant came out.
Started the vehicle, got it to op temp, bled the system....bled the system....fans cycled. Checked the bleeders one last time, both straight coolant.
ATM I'm cooling it down and will go back to check it all agian.
Also used(b4 system was drained) the paper test strips for exhaust gas, they were neg.(didn't change colour) I can not borrow a pressure tester until tomorrow.

So my finding are: still no front heat, but the rear blows HOT air. So baring any major pressure drops in the test tomorrow, I'm thinking it may not be HG? Maybe the heater core is hooped? what do y'all think?

Response From Tom Greenleaf Top Rated Answer

Feel the hoses when running the front heater core both in and discharge. If both warm that is a good sign. If discharge cold it's either just hot air going thru or probably clogged. Flush that backwards and forwards and note debris if any then you are back to making sure cooling system is really filled again. Why not flush whole system not just radiator anyway?


T

Response From highmfer

I did the flush b4 I installed the T-stat, so it was a little more than the rad. I didn't do a full front to back flush of the system. Rear heater core hoses are hot(expected) front ones are not as hot(more warm) but both very close in temp.
Also did the pressure test today with a universal kit(hand pump and gauge w/ rad cap adapter) system held 13 psi for over a min. LOL, think i might just buy a space heater to plug into my inverter
Thank to all the tips, tricks and advice from everyone. Will post up any head way I make with this POS...I mean vehicle.

Cheers,

M.S.

Response From Tom Greenleaf

The symptom is air still in or being pushed in as vapor from failed gaskets - any that carry combustion pressures or exhaust.
You've done what most would to bleed it out but some just will NOT without a vacuum fill by machine or even more extremes than you've already done.
? By cold do you mean overnight cold or just cold to the touch some time after run?
Squeeze hose trick is usually evidence of air but might be stuck where it will not purge on its own like that.
I believe this engine is known for upper intake gasket issues/failures doesn't mean yours just yet. Look for evidence, pressure test system as well for starters.
A clue is from stone cold (many hours) you can feel pressure in say the upper hose build or watch it with a pressure pump gauge build pressure much earlier than the time heat alone would have expanded coolant. If so that's damning for combustion pressures getting into cooling system.
If you want to try again and bleeding air out you can purposely buy correct temp rated thermostats that leak a very small bit of air past them - then coolant too of insignificant amount either by a notch in the t-stat or some can have what I call a "Jiggle Valve" just for this. It's real slow - know that. The idea is letting just the smallest leak past the thermostat when shut tight.
Heater fluctuations are usually air but can be clogging or other reason. If engine warmed up and changes to cold from OK it's usually hot air or vapor despite being hot doesn't transfer the heat, liquids do.
IDK - If you have exact same issue before and after water pump and thermostat it wasn't that alone so would proceed to check for gasket leakage visible and under pressure,


T

Response From highmfer

Cold as in sat over night. Vehicle was not running either. No pressure in any hoses when stone cold, system builds pressure as it heats up(not overly fast IMO).
When the cabin dial for heat/cold is changed from hot to cold there is a noticeable difference in sound and temp of air coming from vents. The problem is definitely worse after water pump and t-stat replacement. Before it had intermittent heat, now its cold all the time. The t-stat used has the little "Jiggle Valve". I'll try to track down a pressure tester to confirm system pressure build and make sure its holding.

Response From Tom Greenleaf

OK - there wouldn't be pressure and shouldn't when cold as everything shrinks, coolant or air. Take a common party balloon and put in in your freezer see what happens. Same in reverse. Small air becomes large air pocket when superheated especially in area that might be exposed to up to full exhaust heat temps.
Looked for pics of thermostat with "Jiggle Pin" is the name they use most in a hunt for pics. May or may not have anything with a feature for the exact application or very hard to find as most don't know what the heck it's there for?
There's also (too hard a hunt IMO a valved one that doesn't allow liquid thru just air/vapor - never noticed one if one had that so can't expound. Action was like a swimming snorkel idea. Thermostat no matter what has to be correct for the engine - no changes for that and fit as OE. Since this is worse since the pump and thermostat change it could also be if used too much gasket sealer. Many thermostats come with a tiny pie slice wedge cut out for letting air thru as well get covered in gook and defeat it. These items must face highest spot on side mounted thermostats.
You can rule this out by getting it vacuum filled or keep trying. It's a very REAL issue on several engine designs and cooling systems. By rights they should purge out last tid bits and many do, some just wont.
I'll try some pics which are tricky here. Some show, some disappear in time and IDK why!

Hope that one shows with tiny pie slice hole

Hope those show for you to get the concept and why it's done and has been for decades if only to speed up easier engine refilling.
Again, rule it out as by the time you are sure gaskets, heads and intake both in question and do not have to show coolant in oil or vs versa or smoke out exhaust for evidence.
Good luck and high hopes it's easy as just this,

Response From highmfer

Thanks again guys! I have a day in the car port trouble shooting some more. The aftermarket T-stat had the notch, but I'm seriously debating if I even put it to the top.
Once the list is complete, I'll get back and post my findings. Fingers crossed!

Response From Hammer Time

You have all the classic signs of a blown head gasket. This engine is very notorious for this problem.

Response From kev2

a bleeding trick -- raise the front end want rad high point, with the thermostat use a hard asprin to prop it open when starting fill have rear heat on/


better yet check your PM for a idea...

Response From Tom Greenleaf

Interesting idea Kev and would work. Agree HT that this smacks of a head gasket just really want to rule out something causing air or removal thereof.
Yes - Have hoisted front/radiator w caps so high please don't watch! This isn't for just anyone to even do vs getting it vacuum filled now if available for just that. I had (past tense) use of that not owned and may not as retired and have enough stuff around now.
It's me, I hate to blame a larger job without seriously knowing it needs it as sure as I can be,

Response From highmfer

I agree with you guys abut the HG, was most defiantly my first thought. But I really don't want to jump to the conclusion of its not the actual problem. it seems weird that there is no temp fluctuation on my scan tool(no overheating) it doesn't seem to show any classic signs of HG leaking. Or maybe I'm being overly optimistic

Looks like tomorrow is gonna be my day to rip and tear. That helpful PM was very useful kev2, and worth a try. I will post back with any findings as I hate reading through a thread only to find it abandoned and unanswered.

Thanks again to all who have chimed in!

Here's a trick for you to try to check for head gaskets.

Find a stretchy latex glove and put it tightly around the radiator cap with a rubber band. A balloon will work too if it will fit over the radiator filler. Now run the engine until it gets to operating temp and see if the glove inflates with air. The air would be from combustion gases getting into the cooling system

I didn't see Kev2's suggestions and wasn't thinking of rear HVAC on my mind either just adds to bleeding out time and involvement.


OK - you saw the notch. That I find quite common or some bitchy ones make a flaw on purpose.


Whole bull is just plain filling a system even easy ones takes time and cycles of warmed up and cooled off and shops/techs aren't going to usually spend all that time or some do and work on something else OR end it all and vacuum fill now.


Let's not go there but how are you testing A/C making vent temps colder than I'm guessing ambient temps of cold air if close to 1C as you said it really shouldn't be blowing colder as that now brings on another concern. If it can do that the evaporator is colder than that and would frost up, ice up so isn't controlled not to do that.


That could make this an entirely different problem to deal with! A/C if shut down shouldn't interfere with heat request by itself,

have you had this vehicle long- has it heated well for you past years. The past performance would need to be known but.... There is a TSB 00-01-38-011B for low heat at lower eng speeds...also a TSB #03-01-38-013A for lower air flow at vents with full heat....
Is there an auxiliary rear heater? they create exponential bleeding issues.
As tom suggested be sure to use AC Delco t'stat - yes a simple part BUT aftermarket is problematic with it. Might want to recheck the gasket issue, test strips will test antifreeze to help ID exhaust in coolant- Try NAPA for them

I've owned the vehicle about 3-4yrs(since 99000km now at 225000km) no issues with heat or air flow until recent. Roughly 3 weeks ago started to get intermittent heat, cool when idle, warm when driving(b4 3 weeks ago would be hot air) Now the air is ice cold(about +1C outside temp). With dial set to cold, air is noticeably colder, and I can hear the switch in HVAC doors opening and closing.
"Is there an auxiliary rear heater? they create exponential bleeding issues." yes there is the dual climate control. Two separate controls for front and rear(I'm assuming that's what you were referring to?
I'm going to run the pressure test, take those results and figure a parts list. I will replace the T-stat to an AC Delco(because I know it isn't ATM). And try the test strips(good call, completely forgot these thing existed)

Big shout out to this forum and its users! First post for me, 15 views later and two replies with great advice.
Thanks Tom Greenleaf & kev2
