Sounds like your automatic choke is giving you problems. Check to make sure the choke is operating correctly. If it ins not backing off as the engine gets to operating temp it will cause a rich condition and excessive black smoke out the tailpipe and extremely poor fuel mileage.

    Don't know what the problem could be unless I could actually see and hear the truck run. Sorry. You could have a dead cylinder due to poor compression or a burnt valve. There are so many other variables. Do a compression check on the engine and that should help eliminate a few other factors. Good luck.

Rough low idle and black smoke


Bad carb or fuel injection issues- the system is fuel rich (black smoke) and also fuel rich system can make the idle low. Many things can cause this but thses are just a few.

Black smoke>fuel consumption>rough idle


Hi there:
Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.

How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Black smoke from exhaust, rough idle, black soot on plugs


signs of a bad fuel pressure regulator-- the vehicle will run rough, the engine will not start ( usually in the mornings,) many times engine starts but stalls shortly after starting. a bad regulator can result in fouled plugs. replacement is only cure. 1- black soot on plugs-2-black smoke from tailpipe-3- running rough-4- stalling, good-day! repost if need be.

I bought a second car for utility use; B6000, 1994, p/u, standard trans. Only when starting and running when the engine is cold, it runs very rough and difficult to idle. At normal operating temperatures...


a coolant tempurature sensor will make it run to rich if it is bad. run rough at idle, and produce black smoke, engine may stall out. it also causes retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage. good-luck!! if light is on check for problem code. this will guide you in the right direction. if no scanner, any auto parts store will scan for free. repost if need be. have a good day!!
