2004 Suzuki Forenza HELP!!!!!

Showing 3 out of 3 Posts
Question From Cubsfan2112 on 2004 Suzuki Forenza HELP!!!!!

I have a 2004 Suzuki Forenza. A brief history of what I have been dealing with. Back in December I had my radiator replaced by my mechanic. He had mentioned to me that my car was misfiring. So instead of having him diagnose the problem, I figured I could deal with it on my own. At first the car would jerk back and fourth when I would drive around 60-65. Then the car started losing power. I first changed the plugs and wires and the car was still running bad. I started looking online for other problems. I then replaced the ignition coil and that seemed to fix the problem for about 2 weeks. Then the car started running the same way again (jerking and loss of power). I purchased the coil online and paid $30.00 for it. I then read that cheap coils are the wrong thing to buy so I went to my auto parts store and bought a $120.00 ignition coil hoping that, that was the problem and it wasn't. I then changed the throttle position sensor and that didn't fix the problem. I then took my car back to my mechanic and he said the problem was a clogged catalytic converter. He had taken off the o2 sensor so my car would run better but it would be very loud. So I ordered a catalytic converter online and got someone to install it for me. I put the o2 sensor back on and went for a test drive and like usual my car had no power. Like I would be in 5th gear on the freeway barely going 50 mph. My cars check engine light came on and I took my code reader to it and it said po300 code random misfire. I took the o2 sensor off again and power was restored with the loud sound again. The po300 code always seems to go away with the o2 sensor off. When I put it back on the po300 code comes back on. So I heard that I talked to Scotty Kilmer online (he does a lot of troubleshooting videos on youtube) and he said that I could have a clogged muffler and I should get a pressure test done on the muffler and maybe have the muffler replaced. Well I went to my local muffler shop and he said that a muffler can't get clogged and that the problem is probably some chip in the computer. I wasn't sure about that answer he gave me. So I kept reading online about these issues and decided to replace my o2 sensor. I did that yesterday and drove on the freeway only to experience the same problem every time I put the o2 sensor back on. Lack of power and the po300 code came back on. So I took the o2 sensor off again so I can drive my car. I don't have much money and that is why I've been driving my car like it is. After changing the plugs, wires, checking for vacuum leaks, TPS sensor, cat, and o2 sensor. I am running out of ideas. Any ideas of what else it could be? Please help me. Thank you.

Scotty Kilmer??????

Don't get me going on that idiot. He is a complete moron.

You could have had this professionally diagnosed 10 times over with the money you have wasted throwing part at it.

Response From Tom Greenleaf Top Rated Answer

"So instead of having him diagnose the problem, I figured I could deal with it on my own."


That was mistake #1. Scotty Kilmer! Get real, that's entertainment for the gullible. You've replaced enough stuff and spent enough on items that were not the problem with wild guesses without diagnosing anything now you'll confuse the your first chance at just diagnosing it and fix what's wrong.


Why did you replace the radiator? No doubt that was the beginning and source of your problems with lack of coolant and overheating so let the first guy diagnose it,

1986 Suzuki Sierra loses power under acceleration

Question From Sebastian96 on 1986 Suzuki Sierra loses power under acceleration

I bought a 1986 1.3L Suzuki Sierra last year with 53,000kms on it, besides it overheating when I drove it home due to a leaking radiator the car went relatively well.

Since then I replaced the radiator, bushes under the handles of the transmission shifter handle and the transfer case handle (hopefully that makes sense), new fuel filter, new oil filter, new heater core, had the alternator tested and it's working fine, all new oils.

After doing all that I took the car for a drive and when I got into 3rd/4th/5th gear the car began losing power, engine revs and speed started dropping. I was told I should replace my spark plugs, and I did. After that the car went fine in 3rd/4th/5th however except this time I can push the accelerator down about 90% of the way, if I push it the last 10% the car starts to lose power, if I let it off a little bit to within the 90% it starts accelerating again, foot down the last 10% and it starts to lose power.

I have noticed a spark outside the distributor, and also I rechecked my fuel filter and after taking it for a test drive the fuel filter is really dirty again! I pulled off the fuel pump and I think it looks okay, the only thing worth maybe mentioning was there was a slight mix of fuel and engine oil and the rocker arm was quite hard to push in and out.

Response From Discretesignals

That vehicle is not sold here in the states, so advice is limited.


If the fuel filter keeps clogging up, maybe you should pull the fuel tank and see what is going on in there. You could also have a rubber hose deteriorating. What ever is floating around in the tank could end up in the carburetor, so you may need to go through that too.

Another possibility is a restriction in the exhaust. If this has an O2 sensor you could screw in a back pressure gauge to see if you have excessive back pressure. If it doesn't have an O2 sensor, you might have to weld in a bung or find another way to measure back pressure.

Response From Sebastian96

Well America released the Suzuki Samurai, which is the American equivalent basically. If that helps?

Also is there any simple way of checking the carburetor for signs it may need cleaning, I really want to try and make sure I fix what actually needs fixing because I have seen so many different suggestions, and I could spend a lot of money before finding the issue.

Response From Discretesignals

You did buy an old vehicle that has problems, so your going to be spending money to keep it alive.

You really need to find out why the filter keeps getting trashed. That would be your first priority.

There is an art to overhauling or doing carb work. If you suspect a carb issue, the only way is to take the top off and look in the bowl to see if there is trash in there. You could have clogged air bleeds or mains or any number of issues.
Some carbs have primary and secondaries. If it runs fine on the primary and you gun it and it goes into the secondary and bogs out. That is a sign the carb needs attention or you have a fuel supply issue.

Response From Sebastian96

Okay thanks a lot for the suggestion!

Do you think this would be an appropriate method of going through it?

I was thinking I'll pull the fuel tank out, flush it by just tipping petrol through, replace fuel lines, replace fuel filter, then if I'm still having issues perhaps change fuel pump and then lastly carburetor? also could I put a small filter between pump and carburetor so if I do have the same issue I can avoid getting the carburetor dirty?

Response From Discretesignals

Sure you could install a filter between the pump and carb. I think you have a good plan with pulling the tank and having a look inside.

Response From Tom Greenleaf

Fuel in oil too! Could be trouble with lots and must have good clean fuel delivered to a very expensive carb just looking at it gives me a headache and used to redo plenty but not so much the 1/2 and 1/2 with electric controls - better one or the other.


Take a look.........
/
That top plate MUST open wide when warmed up quickly (choke) or it will dump raw fuel all the time and bog out - any would just this is a pita now for any parts if needed and insanely expensive BTW. Like $500US - yikes! Check around if needed in your area for non US specs also.


See if you can find a see thru fuel filter inline between pump and carb or I would for this,

Response From Sebastian96

Thanks for the suggestion, I pulled the top cover of the carb off and I pulled the accelerator cable and as I pull it, it slowly opens up and I can see a squirt of petrol enter the carb everytime I pull it, although it does look a little dirty inside my carb I'm not sure if it's enough to cause issues but I could be wrong. Also I noticed my muffler is making a rattling sound when I hit it with my hand, is that normal?


Response From Tom Greenleaf

Carb is dirty so clean that up. I'm worried about the fuel in oil most & problems from that to be ruled out. That alone can ruin the engine and you can stop if so and seek other solutions. If light enough oil or way too full oil would be harmful to a disaster.


That top plate when cold if you just tap accelerator pedal should snap shut but push open by a finger - cold, engine off. You should see that plate open upon start and in a couple minutes stand straight up - it probably doesn't and that will be the problem and other problems because of that to be found.


Muffler? You mean it sounds like it's full of rocks or something inside or possible heat shielding rattle from outside it? Inside baffles can rust all out or catch crap from up ahead of it.


I may be off on the wrong thoughts on this but the oil and fuel mixing has to be checked out. Compression check this engine. Looks of that carb suggests excessive blow-by now possibly from cylinder wash. May have all started with a choke issue and wrecked this engine so check as much as you can to pick plan.


If oil is getting in air intake that's a bad sign for this thing engine wise. You need to know before you attack with wasted work if a lost cause and might not be at all just have to know.........

Response From Sebastian96

Yeah well I appreciate the help, I agree. So what do you believe may be the cause for fuel and engine oil to be mixing?

I pulled off the fuel pump and in the head there was a slight mix of oil and fuel, which I've heard is a sign of either a stuffed fuel pump or maybe something in the engine causing it to push oil through the pin that sits against the rocker arm of the fuel pump.

Also, I did an engine compression test approximately 2 weeks ago and I got between 120 - 130 among the 4 of them.

The sound from inside the muffler isn't a metal sound, more along the lines of dirt and maybe a little gravel.

Also this car although being a 1986, has only done 53,000km's.



This is inside the fuel tank, no rust and looked to me little if any dirt, there is a small amount but only due to me accidentally letting some fall in. Which is strange cause after I put a new fuel filter on it, it got probably 10kms before being filled with crap again!



Here is a picture of the muffler, almost looks like its trying to split.

Response From Tom Greenleaf Top Rated Answer

Fuel in oil can happen at the fuel pump itself. It mounts to engine and purposely exposed to oily fumes to lube it and if inside the diaphragm is violated can spit fuel out or into crankcase - mixed and the oil gets so thin it's no longer a lubricant or very good at it. That's a concern.


For compression that seem low so you need to add a squirt of oil (was hoping you'd post before oil squirt and after results) then pressures will no doubt spike up quite a bit as that seals rings to cylinder walls that could be excessively worn in turn blow by and the oil in your intake. Those are horrible signs for an engine. Doesn't take many miles/kms at all.


Muffler is junk and any pipes that go with it. There probably was a heat shield long gone where it's the worst now with straps. I doubt that's the up-front problem with this in general.


I just want you to know realistic engine condition so YOU can decide how far to go with that one or another if need be.


That or maybe some tricks to just get it to run OK for a decent while - that would always be what you expect for what investment in work on it.


Fuel pump again - get rid of that now as it real high on the list of the gas/oil issue and shouldn't be expensive or difficult. New oil and filter once again too if still driving this, or count on it for transportation,

Oil leak and odd sound...

Question From itsmole on Oil leak and odd sound...

I don't know too much about cars, so will do my best to explain. Any tips or advice would be great, as I don't want to go to a mechanic and have them hit me for more than I really need

I recently noticed that my 2005 Suzuki Forenza was leaving small oil spots on the driveway. I opened the hood in the morning before work to look and all seemed mostly normal aside from a few small oil drips collecting down near the body body part of the car. So, on my way home from work, I noticed that my car seemed louder than normal but only at low RPM and lower gears (its an auto trans). It almost sounded like the noise a muffler tip or exhaust leak would create, but coming from the front of the car and only at the lower RPM in 1st gear or so. When I opened the hood, I noticed that there was a decent amount of oil leaking from the engine case, along the seam where the top cover attaches. It is mostly on the drivers side as well and a little in the front. I looked down and saw the puddles were building up and looked like oil, but I couldnt exactly tell...liquid may have a slight red tinge to it (rust or trans fluid?).

So, aside from the noise, it seems the oil is leaking out while the engine is running and then once parked for the night, it slowly drips down. Someone I know said it may be the valve seals/gaskets have gone bad allowing oil to leak out. Does anybody else have any idea what it could possibly be so that when I talk to a mechanic, I can give him a little better info.

Thank you!

Hopefully your mechanic doesn't need you to describe where oil could leak out of an engine. Your mechanic should be able to get the vehicle in the air and visually see where the source of the leak is coming from. It doesn't take a rocket scientist to figure it out.

Response From Tom Greenleaf

First post here said you don't know much about cars but somehow need to explain what might be wrong to a mechanic! Huh? If you don't trust a particular mechanic why would you go there?

Just tell them what you notice wrong and let them tell you what is needed to fix it. The "friend of a who knows" thinks it's this or that crap if so good let them fix it. I suggest not waiting with a leak and noise together you are probably wasting time to get this fixed before it gets real expensive or a disaster,

Response From Hammer Time

You have a whole paragraph telling me about oil leaks and engine noises but I didn't read anything about you ever checking the oil level. Are you waiting for the engine to blow to find out if you have enough oil?

Response From itsmole

Oil level is okay, checked yesterday. Oil was changed 2-3 weeks ago with inspection. Also no smoke or lack of power, no grinding, knocking, tapping, etc associated with low oil. The sound is a low pitch rumble only at low RPM ang gear. Sounds similar to an exhaust leak as I said.

Response From Hammer Time Top Rated Answer

Something is leaking pretty heavily so maybe you should check the trans fluid, coolant and power steering fluid to find out what you are losing. As far as the noise, you'll need to pinpoint it down a little better as the where it's originating from. Maybe you can record the sounds and upload it to youtube and post the link here.
