    I have had this problem for about 60,000 miles (5years) now after I flushed and filled my coolent. So I thought ia shorted something expecially after reding the codes, I have low voltage to the fuel pump, throttle position switch, fuel pressure regulator, and three other things (all low voltage) I cant remember because it has been so long. It has a new battery, altinator, plugs and wires.It smells of unburned gas in the exhaust. Mine also wont stay running without me revving the engine after it turns over after you have opened the gas cap at all.

HTML clipboard If you can smell gas ONLY when the engine is running, then the gas didn't get burned completely. It could be the combination of the computer, oxygen sensors, and/or catalytic converter is going bad. If you could smell gas when it's parked, you might want to take it to a mechanic to have your gas line checked for leaks and for pressure test. Here's a website that talk a little about gas smell www.mycarsmellsbad.com good luck.

I smell gas


Sound like it could be quite a few things. Off the top of my head I would check that the car is firing on all cylinders. If one has gone down you will have fuel travelling along the exhaust pipe, which could explain the smell. If you have lost a cylinder it will be as rough as a badgers B*M, and you will get rubbish mpg. Check if you can smell fuel from the exhaust pipe (Not while the car is running I don't want you to get carbon monoxide poisoning), just give it a quick start and a few revs first. If it is or anyway If you take the plugs out one at a time look at them to see if they are wet and smell of fuel, (After a quick start and a rev). Check your air filter as well you could even take it out and see how it runs (Not for long just a quick blast) see how you go with that.
Good Luck

White smoke and foam in the gas tank indicates antifreeze leaking into the engine somewhere. Do you smell antifreeze? You may have an engine seal leaking, most likely head gasket. It may be affecting the various engine sensors.

Car Starts Really Rough.


Check the fuel/air sensor and air filter. When you first start the car only press the accelerator pedal once. If while turning the ignition switch you here a grinding noise that would be your starter going out. The smell of fuel signals that your car is either flooded from pressing pedal or fuel mixture is incorrect. Hope this helps.

ROUGH IDLE,WET SPARKPLUGS,KILLS


The Symptoms tell me it is a head gasket. A leaky or bad head gasket would cause all of the problems that you mentioned.

Burning water causes White Smoke, Burning Oil causes Black Smoke. The oil and water are mixing with the gas in the cylinders and causing it to run bad. Pull out the dipstick and look at the oil on it. Does it look like good oil? Or does it look watery and or foamy or grey colored. Open up the radiator and look inside, do you see oil?

This seems almost text book to me... I would have someone local to you to have a look at it to be sure.

Well, you have to let diesels warm up before you drive them so the engine gets warm and it may not sound right at first because if its not warm the compression gets off and doesnt fire right. If you try to give it too much gas before its warm, extra diesel will get in the cylinders and misfire. Then when it does fire, there is a lot of extra fuel in it so that causes the smoke and smell. You should always let it warm up for a bit before driving when you havent driven it for a while.
