Okay per my previous post i am having an unusuall bumpy idle, Only at idle is this an issue, car run's perfect while on the road, in fact since i cleaned the injectors it hall's ass.
The Engine HAS NOT stalled out once, nor has it hesitated to go when you hit the gas.

At The rear exhaust you can hear what sounds like a miss. When the A/C is on the bump pretty much goes away, though this is only because of the upped idle.

Compression Check give 140-150 accross all 4, Keep in mind the head has less then 5K on it

New Head 210K, PO Blew Head Gas Rear #4, Replaced Head and Gasket.
