Engine Performance problem
1993 Pontiac Sunbird 4 cyl Front Wheel Drive Manual 89000 miles
Car just started running ruff all of a sudden. Seems to be miss firing in idle can drive the car and in lower gears 1-2 seems ok with intermittent bursts of power however in the upper gears 3-5 it has little power and slows going up hills. Have a code reader and get no error codes. Checked the injectors with an ohm meter all read about 12.8 ohms. Checked the signal with a node light and all are getting a signal. Pulled the DIS module to have it tested but was told they could not because it has the coil and module all in one. Cost of new was 260. Read that maybe the crank sensor may cause this. Any suggestions?
have the same problem?
