Suspect cracked injector(s). I drove a truck with cracked injector and it billowed black smoke. Power loss can be anything from a sensor to a clogged filter. try changing the fuel filter.

Had exhaust manifold replaced since then my 2001 caravan bucks and blows black smoke little to no power


if you replaced the manifold because it was cracked the look for a plugged cat convertor..the cracked manifold was probably letting the exhaust escape..now it builds too much back pressure

Black smoke from tailpipe, loss of power, anyone know?


What year, make and model car is this? Most likely, black smoke is
usually a carburator problem. If it's fuel injected, black smoke can be caused by 1) leaking or faulty fuel injecters, 2) faulty choke, 3)dirty air
filter or 4) faulty distributor cap and/or rotor. Hope this helps.

I ran my chev. 1990 pickup out of oil and now it smokes so bad. and i think my fuel pump is going out but not sure??


Sounds like you may have ruined the piston rings and this is allowing oil to seep in to the combustion chamber hence your smoke. Or if it overheated when you ran out of oil it is possible that you have a bad head gasket now. Check both your coolant and oil for signs, oil will have a white froth, or darkening of your coolant. Hope that helps you.

1993 lumina euro is blowing black out of tailpipe smells gas


Black smoke is unburned gas. If the car is running fine besides the black smoke, it's most likely the Coolant Temperature Sensor. The part is roughly $20 and an easy fix.

PS- I'm guessing your check engine light is on...

as far as the black smoke you have rich air/fuel ratio. check you air filter and for vacuum leaks. as for the windows i had one just like it with the same problem. get some circut board cleaner and take the switch in the door out and saturate the little circut board and contacts. thats all i had too do to mine. hope this is help to you

Jeep running rough; black smoke from tailpipe; dying occasionally


Have you taken a spark plug out yet? You may have fowled them out. if they are not clean and have a whitish tone to them, then they need to be replaced.
