After replacing head fuel injector plugs wires and fuel filter the motor skips when idle any ideas garage is scratching there heads?

Answer 1

What is the make/model/year/engine size, how many miles on engine, how long has the car had this problem, and has it been sitting for any extended period of time? Also, did they completely replace ALL fuel injectors, and have they changed any/all the spark plugs too? Please answer all these questions as detailed as you can be.

Answerthe engine is a 1995 2.2ltr with 185,000. It started out running fine, had 30,000mi since last tune up, a plug got broken when removing it. The head was removed to get plug out and that was when the head was found cracked. New head was installed and new lifters, pushrods and rocker arms. When th car was started, it had a skip in motor. Removed plug in #4 and found it wet, disconnected injector, after instaling plug, and it ran the same, only injector #4 was replaced. The fuel filter was also replaced. It has spark, removed plug to check, Installed 4 new plugs and wires, gapped at .060. I haven't done a compression test as of yet....plugs seem to look fine after running car for 30 miles...just got skip in it. No hestitation under acceloration just when idling in park, and when stopped.
