89 GTA 5.7L Rough Idle
I've been having problems for a while now, at first it was intermitting now its all the time. I wuld be driving and it would be running like a champ, but if I shut the car off and restarted it, it would run real rough and have no power whatso ever. Now its doing it all the time, also i had to put a new battery in it cause it was going dead. So, I changed the distributor cap, coil, module, alternator. It still has the problem. I'm thinking its the plugs, it feels like one or two of the cylinders aint fireing. The weird thing is that it was intermitting, now its not. Any thoughts if installing new plugs and wires dont fix it? I've read that it might be the IAC, but i got no idea what the hell that is or where, is it easy to change or fix? Thanks for your help.
