Black exhaust smoke indicates a fuel-rich condition; not all of the fuel is being burnt.
The first thing to check is the air filter. If the engine can not pull enough air through a dirty filter, all of the fuel will not burn. This will also cause stuttering, and stalling. if the filter has not been replaced in 10,000 miles, it will be pretty dirty, especially if you take your Jeep off-road.
Other possible causes:
# Dirty fuel injectors, # Worn spark plugs, # carbon build-up from long-term excessive dignity. Let me explain the last one: I you drive in a very sedate manner for several thousands of miles, carbon can build up on the cylinder walls and on the valves. A sudden, full-throttle acceleration will burn the carbon build-up, causing black smoke and stuttering. The cure is to get on an appropriate road, and do three to five full-throttle runs to about 60 MPH. This burns the carbon out, and restores performance. A CAUTION: Do not try this with a dirty air filter. It will only make the problem worse.
Good Luck!
Have your fuel filter checked first. If that doesn't solve your problem, then have your catalytic convertor checked.
Check for clogged converter (1 possible cause)
Could be the transmission!!!!
u can usethe word stutter in a snetence like this: i stutter a lot when speaking.
You would not be considered a stutterer if you only stutter at certain times. Those who stutter all of the time do stutter worse in highly emotional situations.
Carbureted, so what? What year is it? Does it have points or HEI? Several things come into play here, as well as a worn out lifters/camshaft.
