DTC - 22 Throttle position sensor error (signal low), is tps connected?
DTC - 23 Intake air temp sensor error (low temp indicated) check and make sure the sensor is connected
DTC - 43 Knock sensor error, ignore this for now, will not cause rich run.
DTC - 53 System voltage too high, check reference voltage from PCM, it should be around 4.5 Volts, this could be the cause of all your problems, the computer will need to replaced almost for sure.

1991 chevy van g20 blowing out black smoke


The most typical reason is that the fuel pump is getting weak. You may think I am nuts. Let me explain. The fuel injectors, on a throttle-body system, need pressure to atomize the fuel properly. With low pressure, the fuel just runs out of the injecot nozzles and puddles in the intake manifold. Then it literally "runs" into the engine. It does not burn properly and produces alot of black smoke. Fuel mileage goes way down, also. Replace the fuel pump and fuel filter, and you will be amazed. Good Luck.

It has a bad mis and running rich dark foul smelling smoke what's wrong? 1991 chevy v6 s10


possibly a faulty injector for the miss but if you have a head/headgasket problem it would account for the exhaust. Do a compression test and radiator pressure test to eliminate that area of concern

Have 82 ford truck f150 runs for abut 5-15 mins than dies getin gas chang full pups two times same thant runs and die


Hmmm...maybe piston ring failure, valve seal failure, rich air/fuel mixture or maybe a head gasket (however that is normally white smoke due to coolant burning instead of oil). If it's so dark that it's almost blue then I can tell you that somehow oil is getting into the cylinder and burning alongside the air and fuel. Your best case scenario is that the engine is running rich (Rich:Too much fuel, Lean:Too much air) and the smoke is a dark grey to black color. CAUSES OF SMOKE

91 Lumina won't stay running; see lots of same question for same car but no problem solvers....Please help.


On electronic fuel injection pumping an pumping an pumping the gas pedal does nothing without the engine running ! Pushing the gas pedal to the floor will cause the PCM - engine computer to go into clear flood mode .

You have some very interesting ideas here , but not really how it works or is !

The vehicle will go into closed loop fuel control when the engine coolant temp reaches a definded temp an the O2 sensor get hot.

She would run for a couple minutes and die which is open loop when running, closed loop is when the sensors kick and it would die. Pulled spark plugs, they were black meaning no spark. Can only be 2

Black spark plugs indecate a rich condition , over fueled , wet spark plugs indecate no spark .

It could be, but you had a mechanic working on it right? Ignition control box? does it run better now?
where is the smoke coming from, exhaust pipe or under the hood? Did the mechanic check the fuel pressure and replace the fuel filter? Did they check for vacuum leaks? These should be the first thing they need to check.
