Hey all, I have a problem with my 1995 Verada 3.0L auto. I snapped the timing belt and stuffed the heads well and truely. I have since replaced the timing belt, heads, water pump and all the other stuff that needed doing. The problem I have is the car wont idle smoothly. I have had a local mechanic look at it and he said that when they earth the plug to set the timing, it stops hunting. So another ECU was put in but it is still hunting for idle.

Any suggestions on what I can try would be appreciated as I need the car to get to work.
Thanks in advance.
