It may be the coil for # 4 cylinder, or a bad plug wire.

Why do we keep losing power?


You don't mention replacing the crankshaft position sensor but it could be the source of your continuing problems.

No voltage on crank sensor grand am 2001 2.4


The crank and cam sensors produce ac voltage that is sent to the computer. There are magnets or components on the crank and cam that the sensors "read".
The problem could be the harness between the sensors and the computer, or a mechanical problem like a timing chain or gear.

My jeep cherokee has a loss of power and with the check engine light on, I fixed the cam sensor but no **** luck. my mechanic change the coil pack and again no such luck, What could it be?


I put my money on an O2 sensor. I had the same problem last winter if its what Im thinking. I would just get sudden powerlosses during acceleration. I believe there are 3 different sensors within the vehicle so make sure they all get checked. They ALL have to be working properly. GL :)

2004 pontiac grand am replaced O2 sensor, spark plugs, plug wires and fuel pressure regulator. starts easily. idles very rough. When accelerating car runs well. When cruising on freeway with engine...


Idle air control motor(IAC). EGR valve. And vacuum leaks to include the brake booster and if you have a plastic intake, that too. this is a start there are other things that will have the same symptoms. let me know

1992 pontiac grand am no acceleration, a rough idle (engine miss)


Does it have the 2.3l Quad 4 engine? If so replace the plastic piece that the coils go into, they go bad and leak spark to the cam towers and then you get a nice one or multiple cylinder misfire.

Jeep Grand Cherokee engine sounds like it's missing


i think your barking up the wrong tree here,it sounds like it needs the computer on it and someone to drive whilst the other person monitors it or a rolling road.Its all very well changing this sensor or that one but without knowing exactly you could waste more money than what it would cost putting it into a dealer with mechanics with product knowledge
