Hi to all, first post, I have a problem I hope someone can help with. My daughter has a 2002 Galant 2.4L 4 cyl auto. 111, 000 miles. all of the sudden the other day, while at a traffic light, it started running rough, the check engine light came on and it started pinging (detonation)very badly on acceleration to the point where it is barely driveable. We have it down to the local mechanic and he is telling us the motor is junk. says cyl1 and 2 have 170lbs of compression and 3 and 4 have only 80 and this is the problem. suggests new motor for $2500. I don't beleive the motor is bad, tired yes. The motor idles ok , doesnot skip, doesnot smoke, tailpie is clean, the pinging gets worse as the motor heats up and has been trouble free until now. It acts just like the timing is advanced all the way. I feel it is in the ignition somewhere. any advice or suggestions are welcomethanks Dave
