Bumpy Idle Continues 700 1987

1987 765Ti

Okay per my previous post i am having an unusuall bumpy idle, Today i decided to go out and tackle some other things on the car to see if i could trace it down any. 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

Checked Turbo Hoses No Issues There. And Turbo Is Performing Per Spec's.
Replaced All Vac Lines That were 1 or more years old.
Checked Plug's Some Carbon Build Up.Cleaned and reinserted, Plugs Less Then 1K
Wires Are New, Less The 1K
Dist Cap And Rotor New Less Then 1K
Replaced Dist
Cleaned TB
Timing Set Perfectly At 0 and stick's there even when bumping
Replaced IAC
Cleaned Injector's yes i removed them to do this.
Replaced Coil
Swapped Out RSR With Known Good One, i believe that the device drivers side inside fendor mounted to the heatsink.
Swapped Out The Unamed Device Drivers Side Only 760's Have Them, Looks Like a pack of fire crackers

I have not replaced the Fuel Filter at this time as i would assume if im starving for fuel at idle id be starving at any other speed, or running Lean.

Thought's Anyone Before I Start Replacing The Expensive Sensor's?

KANE, This is the Tan 765 i had at Dyno Day The performed better then fac spec's go figure 1 week after that this start's.
