i have a lot of smoke coming out of my car?

Question

Answer 1

It's likely your chokes have jammed on. Is it getting through a lot more petrol than normal? If so either your chokes are jammed and need replacing or your computer has corrupted its program. I had the same fault with my Jaguar XJR. The fault that occurs is that the computer program gets corrupted and gives the wrong information to the engine, meaning it gets told to push maximum fuel into the injectors all the time.

If its a newish car the manufacturers will probably pay for the re-programming out of courtesy as it's normally their program that has failed.

Answer 2

There's some patent rubbish on here, amidst the answers from people who DO have an idea. Let's get a few things straight.

Blue smoke is from burning oil, BLACK smoke is as a result of an excessively rich fuel/air mixture. The fact that you mention a petrol smell confirms that.

It depends on your car, but there are many solutions. I'd take it to a technician to get it sorted properly.

Answer 3

black=oil
blue=lots of gas
white=antifreeze

so it could be oil or oil and extra gas. Pull one of the plugs, clean it take a digital picture. Put it back in slowly rev the engine up then back down. Stop the car, take out the plug take another picture. White on plug means oil, black means too much gas. then do what everyone else says. Sorry cant help with computered engines, only good with old carbed ones.

Answer 4

black smoke wont be the head gasket. Black smoke will be FUEL!! you are dumping to much fuel that isnt being combusted fully. could be a couple things, sensors, bad injectors, bad plugs, timing out of wack etc. BUT it is DEFINATELY fuel, not a head gasket. Got any "service engine" lights on? also, check vaccum lines under hood, also air filter is a good start.

Let me know if you need anything or have any other questions!

Answer 5

White smoke oftentimes is from antifreeze. examine your coolant point. It does not take a lot to smoke. in spite of if this is agasket, this is purely not so stressful to repair. whilst idling the vacuum sucks antifreese into the cylinders, once you upload capacity the warmth vaporizes it. If adequate antifreeze gets into the engine it is going to snatch the rings and actually make a multitude. i offered an engine actual low fee through fact of that when. oil smoke is bluish.
