White smoke?

Ok, so for the past few months that ive owned my lude it didnt have an exhaust from the axle-back. Then recently it all rusted off right up to the cat. Yes, i just got new piping and muffler welded on, but ever since then, ive noticed a burning smell-gas. And when sitting at a stop then accelerating, whitish smoke puffs out my exhaust, note that it is not constantly coming out while driving though. Ive checked my antifreeze, oil, all that good stuff and it checks out. Ive gotten a cel code for fuel supply system, could it be my fuel pump? Also pulled one for tps, could that be causing me to smoke? I just changed out my spark plugs as well. Any ideas would be great here guys, other than the smoke my car runs great with 162k on it so im lost

White smoke means water in your engine iirc.

Re: White smoke?

found this via google..

Engine Smoke

Puff of white smoke during cranking, before the engine starts; cold engine; gas or diesel. This smoke is unburned fuel vapor being pumped out the exhaust pipe. The white is tiny droplets of fuel. In a gas engine, the spark plugs aren't firing, or the fuel mixture is too rich to ignite. It may mean the choke plate is stuck closed, or a load of bad gasoline.

Steady white smoke; warm engine; any air temperature. This is bad news. The engine's coolant is leaking into the combustion chamber and creating a steady flow of steam. Caused by a leaking head gasket or a crack in a cylinder head, most commonly in the exhaust port area. Usually requires serious surgery on the engine.

Re: White smoke?

Thanks for the input guys, i'm going to run the tank close to empty and fill her up to see if thats it because i haven't been down past a half tank in about two weeks. Also gonna give her an oil change and hopefully my problem will clear up!
