2003 Cadillac Escalade

Question From VivaLasVegas on 2003 Cadillac Escalade

Hello all!

So about a week and a half ago, it started raining. Here in Las Vegas, this is an opportunity for fun that cannot be missed. I took my 2003 Cadillac Escalade out with my girlfriend, and we found a puddle that was about 5-7 inches high and about 3 blocks long..... Like an idiot I did a U-Turn to maximize the fun.

The Caddy died in the middle of the puddle, but we got her started after about 10 minutes of just sitting there. After it started, the idle was extremely rough, and did't get better with acceleration. I let it sit there for a full day before starting it, but the same problem ensued. I took out the spark plugs, and started the engine without any water shooting out, replaced the old plugs with new spark plugs, changed the wire set, ensured all cylinders were sparking, dried out the air filter, and now changed the MAF sensor. I also put two bottles of HEET in the tank, and a few ounces of sea foam in the crankcase. The codes that are still coming up are P0171 (system too lean) and P0300 (random misfire).

The vehicle fires right up, but as soon as I put it in gear, the RPM's drop to the low 500's, high 400's. When I try to press the gas pedal down to the floor, it sounds like the "little engine that could" but there is a severe lack of power, and no gear change until I back off the pedal. The zero to 60 time is probably close to 45 seconds or so. Also, my gauge says that I'm getting 6mpg from the usual 15.5-16. The idle has gotten better right when I first start it, but thats about it.

A little background on the caddy, there is also a little leak somewhere in the caddy. Whenever I try to fill up the fuel tank all the way, it starts leaking out from under the vehicle (not where you put the fuel nozzle in). I'm wondering if there is a possibility that somehow enough water got into the tank where the HEET wouldn't even be effective, and also cause the P0171 and P0300 codes.

Any help would be greatly appreciated.

Response From Hammer Time

That was the most idiotic thing I ever heard of. That very well may have cost you an engine if any water got pulled into the intake.

Response From VivaLasVegas

So my question is, what is the next step.The vehicle starts up, and is able to be put into gear. There is no arguing that it was a stupid mistake, but I'm trying to fix it.

Thanks for your help.

Response From Hammer Time

Fist check to see if the air filter got wet and if it did, pull all the spark plugs and do a complete compression test to find out if you bent any of the connecting rods.
Dry out everything with a blow dryer.

Response From VivaLasVegas

Thank you! I will definitely get on that. I appreciate your quick responses.

Response From Hammer Time

For future knowledge, driving through deep water can take the entire engine out to the tune of about $8K in a heartbeat.

Response From Discretesignals Top Rated Answer

"Oh honey, what a beautiful view. You are so romantic..."

?w=300

Response From VivaLasVegas

I'm definitely going to take it to get a compression test. However, there is no abnormal engine noise at idle or at high speed. It just feels like there is no power.

1993 ford ranger question please help !!!

Question From fokes123 on 1993 ford ranger question please help !!!

I have a 1993 ford ranger 2.3 and i am wondering if i can fit the k&n 57 Series FIPK cold air intake. The oldest year they have is 1995 ranger 2.3 and i am wondering if it would fit my 93 ranger. Also just to make sure with this k&n cold air intake, it would pass smog and be street legal? Thanks!

Response From Hammer Time

Yep, that cold air intake is just a waste of money.

Response From Discretesignals

Save yourself some money and make your own custom cold air intake.


Response From Hammer Time

I don't know how they call these things COLD air intakes when they pull in the superheated air from under the hood. Just a way to take your money.

Response From Tom Greenleaf

OK - went a bit nuts but it's a serious misleading as bad as any Sham-Wow infomercial.
People: Gas/fuel doesn't like COLD air dag nabbit! If too cold it would never atomize (evaporate) to be able to work in time. All sorts of efforts are to warm air not cool it up to putting strong electric heaters under throttle body or carbs then AND run total exhaust heat as well so evaporating fuel (gets cold just doing that like sweat on your skin) can even ice up so it's making itself cold anyway and has to be corrected or you'd just flood out.


No clue how these scams get out there and not pulled from the market place instantly?


True: Cold air has more density (heavier) than warm air - Google out what a hot air balloon is lifted by


The end all is if any of these tricks worked at all or had any benefit it would be designed into the engines to begin with.


This and a ton of bullcrap sells so they keep making it. If it floats your boat go for it but don't complain when it's all worse than before you messed with it,

Response From fokes123

Thanks for all the help guys..... Dont really need your guys opinions on them i really didnt ask. You guys seemed to think i did but you all maged not to answer my question and insted just go on a rant about them. This was a waste of time IMO.....looks like I'll have to take this to a better forum.

Response From Hammer Time

No problem, We won't miss you.

Response From fokes123

Its funny because on your quote it says that you help answer questions but you didnt do jack shit and managed just to bag on me. Nice way to welcome new member on the forum. This is extremely dissapointing

Response From Discretesignals Top Rated Answer

Good information Tom. Like they say, K&N filters are really only good for filtering out rocks...lol. GM came out with a TSB a while back concerning those filters and how they were causing MAF issues. GM stated they wouldn't honor damage done by using those filters. K and N went bananas over that one.

DON'T DO THIS
DO NOT repair under warranty if concerns result from the use of a reusable aftermarket oiled air filter.

The installation of an aftermarket reusable, oiled air filter may result in:

1. Service Engine Soon (SES) Light On

2. Transmission shift concerns, slipping and damaged clutch(es) or band(s)

3. Engine driveability concerns, poor acceleration from a stop, limited engine RPM range

The oil that is used on these air filter elements may be transferred onto the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a result, the Grams per Second (GPS) signal from the MAF may be low and any or all of the concerns listed above may occur.

When servicing a vehicle with any of these concerns, be sure to check for the presence of an aftermarket reusable, excessively oiled air filter. The MAF, GPS reading should be compared to a like vehicle with a OEM air box and filter under the same driving conditions to verify the concern.

Transmission or engine driveability concerns that are the result of the installation of an aftermarket reusable, excessively oiled air filter are not considered to be warrantable repair items.



Have you attempted to contact the manufacture to see if that would fit on your truck? As for passing emissions as long as it doesn't disturb how the air flows through the MAF sensor, you should be alright. To confirm, you should check the laws in your state concerning that.

This really is an automotive repair website dealing with factory manufacture designed vehicles and systems and how to troubleshoot and repair those systems. When you start getting into the realm of modifications and changes to the manufacture's intended design, you may not get good answers.

One good suggestion is to keep the old air intake ducting system just in case you run into issues or you want to sell the vehicle later.

This guy is just sucked in by all the hype nonsense and bogus claims.

He's spouted off long enough. Time to close this.

Response From Tom Greenleaf

Sorry for the harsh approach to what really should be a no brainer and no offence - the advertising is convincing with stuff but real results are so disappointing and costly to buy then don't work and costly to put back to what works!


K&N actually has a competitor for this market that's worse! Look up the Uban lore and myths of assorted products. Some you'll find great reviews but miss fine print that it isn't really tested and don't discuss it can also damage things for using them! Guess the budget for something is better spent not telling you that up front.


Makes this and other magic-in-a-can products a strong seller for the unwary. It's my/our fault to some degree that it's so clearly corrupted to sell this junk it gets taken out on the buyer who trusts the claims.
Graphs probably wont show below and I wont go looking for ones that will but if you really look into results of products of many assorted things never mind a vehicle that took mega thousands of hours to make and design as best as possible or loses a sale of a vehicle when new to another. It's suicide for a company to have an unhappy new vehicle buyer then the icing on the cake is nobody really want them used so really a disaster.


On just this air intake search I just did came up with OE air filter results done by real PPM of catching dirt and the CFM impact of air flowing thru filters and what loss would be expected at they were part dirty vs another. BTW in my hunt AC Delco came out on top of most testing! OE replacement stuff no alterations just quality of the product.


Changing to cold air just is beyond thinking it thru IMO and experience. Used to back when turn a round lid to an air filter upside down and get a neat carb/air intake roar with a load that did nothing but make noise and trash the filter fast but cost nothing and just put it back on properly was all you had to do so didn't do much harm short of getting a dirty air filter sooner and defeat WARM AIR pick up for cold starts and engine's initial time before whole engine warmed up and ran it's best. Do that stupid trick in the dead of Winter you would have real problems.


End all is the change you seek for whatever claimed benefit doesn't work and costs to do it then undo it when you find out. We really (or I was) were trying to warn you of a known failed idea not pick on you at all and did come out bit harsh. Sorry for that.


Try it if you want to find out for yourself. Measure before and after real changes yourself and then if you complain to this company bet you wont even get your money back!


Good luck. We really are all volunteering time and years of experience for that good no other motivation at this site,

Graph if it shows or search it out...........

Accumulative Gain:
“Accumulative Gain” is the total amount of dirt that passed through the filter during the test.

Response From Tom Greenleaf

They even advertise!

With honesty!

Response From Tom Greenleaf

IMO all that is junk you'll be removing later - don't even if it still runs well enough for an inspection it's of no use at all just costly,

Response From nickwarner

You pretty much answered your own question. With a vacuum leak it will not work right, and can give these symptoms that you have. Get the leak fixed and most likely your trouble will be gone.

ok i knew about the erratic idle but didn't know if that would make the car cut in and out at 40mph and above but thanks for replying thnk you very much

Once you have the vac leak fixed ,follow the batt ground cable to front of car . It should be attached to a stud and nut . Unbolt , clean good and reinstall tight .This has fixed more caddy drivability issues than I can remember.

Response From mike93

It's not the positive or negative cables right it's got a new battery but it's right next to the battery? I will try that to thanks for the reply have a great day

Response From Tom Greenleaf

Mike - bit confused here. It's got a new battery - fine. It's no better than the connections and GM connections are prone at the battery and other ends of the cables. Can look ok and not be. They must be good on any car and moreso on this one as RT mentioned,

Response From re-tired

Thanks Tom for a positive reply on a negative subject. Mike, as Tom said that I said. Follow the large negative cable from the battery neg (-) post down to where it is bolted to the eng , it should be a stud just in front of starter. Remove stud and clean area,stud and cable end . Reattach good and tight.

Response From mike93

Ok I understand now sorry about that thank never looked at that but now i will check that thnks a lot guys
