1999 Dodge Intrepid mISFIRING
1999 Dodge Intrepid 6 cyl Front Wheel Drive Automatic 151000 miles
When I crank up my car, it starts misfiring if I turn on the rear window defrost it doesnt do quite as bad. The tachometer is all over the place up and down. Could it be the MAP sensor or knock sensor or what. Can someone help me please.
Engine running rough or misfiring can be cause by the following:
1.Defective spark plug
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
8.EGR valve that is leaking.
10.Throttle position sensor.
11.Manifold absolute pressure sensor
12.Idle air control motor
