SOURCE: my truck blows white smoke
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).

It keeps burning out blower resistors because of the blower motor drawing to much amperage so you will need to replace the resistor and blower motor

i have a simialer problem but i was getting neat fuel out the exhaust as well . i removed the engine because id got a replacement then stripped the old one and as i thought it was a valve timing problem.looking at the engine from the front the cams on the left bank had jumped one tooth out of time so fuel was not being burnt and coming straight through the exhaust.strangely it didnt seem to have a big missfire and idling and smoke got worse when warm.

SOURCE: engine dies in stop and
1999 300M 150,000 Miles
Car dies when coming off acceleration or at idle in traffic or at a stop. I can watch the Tach go to 0 RPM, some times it will restart immediately other times it is hard to start, so far I have always been able to re-start it and Drive on. Does anybody have verified fix for this issue, I have seen posts saying can and crank sensor, throttle body, EGR, and many more ideas... Do not really want to just start replacing parts with the hope that I eventually get a fix. Help...
