Does anyone know what can cause the engine to missfire. I have alredy replaced the distributor, 9mm fms wires and spark plugs. I miss fires the most at 2200 rpms. When I hook my laptop up to the aem computer is seams to be starving for air. any idea's???

Any suggestions would be greatly appreciated.

Starving for air or getting too much fuel?

I would suspect a bad injector or O2's if each plug is getting adequate spark.

One can do a cylinder balance test as part of the self test diagnostics. That would be what I do next. Good luck.

Good luck.

I have replaced the injectors, and both O2 sensors.

I have not done a self balance test.. I will try that tonight.

Check your timing. Might sound stupid but that could also be the culprit.
