Have you checked the condition of plugs#
White smoke is produced when antifreeze and/or water leaks inside the engine cylinder, where the gasoline is being compressed and burned. The smoke is actually steam caused when this coolant gets burned up with the fuel. Any amount of coolant present in the cylinder will produce this white smoke, which will get exhausted out the tailpipe.
White smoke will also come from too much fuel. Or the car has bad o-ring white smoke comes pouring out the tail pipe. Also check head gasket.

1997 sl2 satun started with rough idol now won't start . cranks over and floods. has new fuel filter & air filter


Check the fuel pressure regulator. Pull the vacuum hose off it, If it smells of gas, Replace the regulator. Diaphragm broke and is flooding the engine threw that vacuum line. You'll also need to replace the spark plugs. Gas will foul them out also.

After changing distributor cap , rotor buttons, plug wires and spark plugs on my 1992 Lexus LS 400 i'm still having white smoke coming from from both exhaust pipes when starting after the car sits a while...


White smoke coming from the exhaust upon startup is merely water vapor, which is a normal by product of combustion. I do not believe you have anything to worry about. It disappears after the engine warms up a bit.

Truck starts but stops immediately and smoke comin out of my tailpipe


Well it depends on the color of smoke if it's WHITE; it could be a blown head gasket (check coolant levels and then oil to see if it is milky looking) BLUE: could be burning oil, which could result to fouling plugs (check spark plugs for fouling) BLACK; too much fuel flooded (check spark plugs for fouling)

Faint odor of gas when i start my 93 boneville


It could be flooded with fuel. You could try pulling the fuel pump relay and cranking the engine to clear it out. A mechanic would check for spark at the plugs and also see if the plugs are fuel fouled.
Usually if the oil pressure light comes on the engine will eventually die because the fuel pump stops getting voltage.

2001 Dakota compression loss, smells like gas, white smoke from exhaust


Sorry but this has happened to me before, you might have a blown head gasket. that is where oil and or water are getting in to the piston cylinder and causing the white smoke cause the oil and water is being burnt or boiled.take it to a shop unless you have all the right tools and knowledge to do this job. i cost me like $1500 labor and parts.

Whenever I start the car it smokes than after warming up it stops smoking.


The key is how much smoke? Does the smoke have a smell to it. Are you consuming any fluids, like coolant, or oil?

Tons White smoke that is sweet smelling is usually coolant getting into the combustion chamber.

Less white smoke, especially if other cars are doing it, is normal. For every gallon of gas that you burn, you generate a gallon (GALLON) of water. so this water usually evaporates, but sometimes not. It has little or no smell.

If the smoke is bluish white, that is oil, but usually your converter would fill with oil, and cause error codes, or loss of power. This smell is distinct, but not necessarily sweet.... After the converter heats up, it may be able to burn off the oil and the smoke stops.

What are you consuming, fluid wise, will direct where you go next.
