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.

I have a 2004 Chrysler Concorde LXI 2.7 Eng. Got Check Engine light twice with PO344 code (Cam Shaft). Dealer could not find problem and reset computer twice. Now I am getting error codes PO700 and...

check flexplate,i had a vehicle w/ 2.7 that would throw similar codes(cyl miss code that would change to"cam counter" then weird tranny codes and back)changed cntroll box on trans,coils,cam sensor .ended up being a cracked flexplate that shifted enough it was screwing with crankshaft sensor.the sbec(brain box) was going nuts trying to figure out why cam/crank signals didnt jive so it was basically"guessing" why.its a mechanical failure causing good sensors to read bad,if the codes come back or throw diffrent ones after reset look at non computer causes,dealer should know better.

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 :)

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
