Black smoke comes from exaust when I start. Could it overfuel and how can I fix it if its a new carb on my 88 2e 12valve


assuning there is nothing major wrong, get some forte injector and use it as recommended. I once had a renault laguna diesel fail an MOT test, a roadworthiness test that is, on emissions...it was absolutely chucking out black smoke but the engine ran well. I put 2 bottles of injector cleaner in the half full tank and went out for an eighty mile drive revving the engine in the lower gears. I returned to the testing station an hour and a half later and the engine was running perfectly.
Alternatively, assuming the engine runs well but is just a little smokey, have it terracleaned, this will remove most of the carbon deposits from the engine/exhaust and should increase the life of your engine simultaneously improving fuel economy

Why does engine run rich at times under acceleration?


not enough detail
to get an engine to accelerate , the air /fuel mixture is moved to rich in accordance with engine rpms
the more rpms the richer until the peak rpms are reached
( accelerator pump-power valve in carbies and ECM settings according to accelerator position
black exhaust smoke in diesels
so if you press the accelerator slowly then the air/fuel mixture is altered constantly in relation to the pedal setting
If you floor the pedal then it moves to rich and you get black exhaust smoke until the air mixture is again in balance

Idles rough then takes off good


The emittion of black smoke on start-up is an indication that the fuel mixture is rich, (there's too much fuel going into the engine for the amout of air present in the engine), this could be because the fuel in one of the cylinders is not being ignited (burnt) by the spark plug,or one of the sensors is giving a false reading.

93 Dodge Dakota 5.2 issuing black smoke and running rough mostly in idle. Sometimes she runs perfect. I unplugged the map sensor and she seemed to run about the same or a little worse and it shuts off when...


If you are running black smoke that usually means there is oil and gas mixing together too rich. You probably have a seal somewhere that is gone in the engine.

To fix this try to make the gas mixture a little less (you can change the amount of gas going to your truck, but its better someone who knows what they are doing to do this. You can also run a thicker oil, and possibly put in some oil fixer you can buy stuff at canadian tire or something like that which goes in with the oil and it will help seal cracks and holes in the motor.

Engine idles rough and puffs black smoke out exhaust


on petrol engines is caused by excissive rich mixture,on diesels the injectors need servicing as injectors are not atomizing properly the diesel and just dribling excess fuelwhich is the black smoke

What are the symptoms if my car has a bad engine coolant temp sensor it is a 98 saturn sl1


More specifically you will have trouble starting the car. When the ECTS is bad the PCM reads it that the engine is at -40F. This means that it will dump tons of fuel into the engine in order to warm it up. You may also experience rough idling due to the rich fuel mixture and black smoke from the exhaust (which is an indication of running rich, burnt fuel).

02dodge ram ,running rough, black smoke out exhaust


Take it to an Autozone or O'Reillys and they will test the computer for you. It should have set a code, but you don't know if the code light works so its your best bet. Sounds like it is running rich and the crankshaft module is not advancing the timing.
