Question
I have a 1992 eagle talon 2.0 non-turbo.  The engine was siezed up, because the valves hit the pistons.  We rebuilt the head, repalcing all the seals, valves and pistons.  When we started the car the egine would shake, and it would not idle right.  We then adjusted the timing and still the engine ran rough.  After this, we played around with the injectors and plug wires, and found out when we pulled out one plug, the car lost power.  We did this for each plug, and on the last one, when we pulled out the plug, the car stayed the same and there was no difference in idleing or anything, but there was still a spark.  Can you please help me with my problem?

You stated:

This indicates that you have a problem in the valves on that cylinder.


run a compression test on this cylinder.
