How do you want your problem solved?
Pontiac Grand Am in 1993 to 2.3 cm3 90 kilowatts
While driving engine skips - tearing the engine. When adding gas tearing the engine. I replaced speed sensors on the crankshaft. Is it normal for the start-up, executes an engine cooling fan and even when switched off air conditioning? Ask your advice. Where can be wrong. Next will ask you where I get to know any diagnostic Regulation closely or scanner.

Thank you

I also have a problem understanding question. If your saying the engine cuts-out or has a misfire. How long since a tune-up? Any applicable mil codes, you can check those codes, yourself. Use a gage and check fuel pressure.

As far as your cooling fan, if you use a jumper wire to access mil codes, some models, the fan will run, key on, engine not running. If the fan runs all the time, check codes first, also check coolant temp sensor.
