Hi, I'm courious if anyone can shead some light on my flahing 'check engine' light. Sometimes it's solid and just yesterday it went off for the whole day. The car has a real low idle and rocks at a stop light. I just recently had the head gasket and the ignition coil and plugs and wires replaced but the light came back on. The dealership will check it again at $70 and tell me what else they can do for several hundred more $. They think it might be bad or bent valves and said that would run about $1800.
I'm mechanically inclined and wonder if there is anything I can try first. And, if it comes to it, I also wonder if I can take the head off myself and send it to a shop to have the valves replaced, then put it back on myself.
Any help would be appreciated.
Thanks, Tom
