Could be a bad catalytic converter, check under the car and see if they turn a hot red color.

What causes white smoke to come from the tail pipe with strong fumes while in idle?


A heavy presence of white smoke from the tail pipe is usually caused by a bad headgasket. If this gasket is bad, the vehicle may run rough as well as overheat.

My 92 ford is using excessive gas and has a bad gas smell with alot of smoke coming from tailpipe after i add gas


If the smoke comming from the tail pipe is black your running rich. If thats the case the entire fuel system has to be ckecked out. Injectors could be leaking, a bad pressure regulator,stuck return line ,a coolant temp sensor could be telling the ECU that the engines cold give her more gas. I don't recommend doing fuel service unless your qualified to do so for the obvious reasons.
If the smoke coming out of the tail is grayish you have a bad head gasket. If the smoke coming out of the tail is blue you have engine oil getting into the combustion chamber. keep me posted

Gas comming out of the tail pipe check engine light does not come on.


Chances are it is water coming out this is normal to notice some water dripping out of exhaust periodically as the car runs, If the liquid actually smells like gas i am at a lose I have never heard of this occuring.

I have a 2000 volvo S70 i smell fumes in side car when driving went to get exhaust checked no problem there what can the problem be?


What type of fumes are they exhaust or oil burning.
Exhaust ..Idle engine and put glove on hand put hand over the tail pipe and if engine stops in 20 seconds then the exhaust is good if it keeps running then its the exhaust is your problem..
2 if ex ok then its due to the breather pipe on the engine and it should go back into the inlet manifold to be reburnt but if its not fitted or rubber hose split or broken then thats what you can smell.
So check out under the bonnet and see if you can smell or see any smokey fumes or sucking noise.
Can you see smoke when you start engine.
Let me know ASAP Ron

It's probably the mass airflow sensor and/or oxygen sensors.

Backfiring, rough idel


I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.
