The carburetor needs calibration or changing of possibly defective part, for example, gasket or needles.
what might cause black smoke from exhaust and a bad smell from a 94 ford explorer
If you nicked the oil pan it could cause it to smoke from engine area. Is the smoke coming from the exhaust or engine bay? If exhaust, then I highly doubt it was caused by the curb incident.
Blue smoke is caused by engine oil being burnt by the engine.
Moisture in the exhaust, or a cold running engine.
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
white smoke coming out of the exhaust 99 times out of 100 is coolant leaking into your engine and being burned. if this is the case, a head gasket is blown or something in your motor or head is cracked. oil burns a bluish color with a distinct smell.
Find and fix exhaust leak
I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.
have a mechanic check your turbo.most will tell u that a turbo blows black smoke but can aslso blow white smoke when turbo is malfunctioning
The smell of rotten egg is coming from your catalytic converter that is plugged up White smoke is an indication of water (usually antifreeze) in the exhaust.
Service engine
Engine exhaust turns white from water in the combustion chamber.
