well usually lots of white smoke means that u are burning coolant, the reason that is because the coolant is getting through the head gasket so replace that shizzle on up, took me a day

How would this problem be a headgasket? Please dont comment unless you know what your talking about.....


This code indicates a problem in the cars fuel system.

First off, start with checking fuel pressure. Sometimes a faulty Fuel pressure regulator can cause the ecm to throw this code.

First check and see if you've lost coolant.
Antifreeze has a sweet smell when it burns, so there should be some clue if your ever able to smell the smoke.

Pull the spark plugs and check the condition of each. By comparing them you'll be able to tell how the car is running and if it is a headgasket/coolant burning issue, you'll be able to tell by the condition of the spark plug.

Next as 1sloweg said, check the fuel pressure. Things to check would be the fuel pressure regulator then the fuel filter.

With my old engine, I had a headgasket go south and there was no white smoke out the exhaust. It just ended up pressurizing the coolant system(not a good thing). With the problems your describing (bogging) along with the ECM code it's throwing, it does sound like a fuel supply problem. It's the white smoke that has me confused. If your able to do a compression check, that should tell you if the head gasket is pooched. Feel free to PM if you need more info.

BTW, diesel in a gasoline engine will billow white smoke out the exhaust IF it does run. Quite funny to watch I must say...

could it be water in the gas? that might cause a fuel system error, white smoke and a bogging effect...

Just another thing to think about..... Ive heaard of bad gas horror storys. especially this time of year

No passenger fender liner + CAI = Wet CAI = Bogging in rain

That seems simple enough doesn't it?

If you hit a large enough puddle which you might have ingested enough water into the engine to make it do the things you describe. You might have drowned it.

Pull the plugs and crank the engine over a few times. grab a flashlight and look down into the cylinders, make sure there is no water in them. Even blow then out with some air. If the engine has ingested water, make sure you change the oil.

First thing you should do before you put the car back on the road, get an inner fender liner at the very least.

so you think thats the reason for the car dying?

and what to do about all these codes? could the water have fried the sensors causing the car to runny poorly?

I'm probably not the only one here thinking that ingesting water into your engine is probably not a good thing. As for the sensors, water on them doesn't help their cause.

If it were my car I'd clean the air filter, put your stock intake back on for the winter if you have it and get that water out of your engine. From there if the car runs you can pick on the sensors and "problems".
