High Idle at Operating Temp

Well, just added a 3" turbo back exhaust. Removed the Split Air Pipe along with the ACV and blocked those off.

I am thinking about just blocking off my BAC valve but don't want to do much more until I get my idle problem fixed.

I did a check on my TPS and it shows 1.0 then once at full throttle it is at 5.0.

The car before adding the mods would do the normal warm up at around 2000-2500 rpm then drop down to 750 or so at normal temp. Now, it does the same 2000-2500 rpm cold start but then drops to 1000-1500 rpm and just stays right there.

Any ideas would be greatly appreciated.

Car is an 87 Turbo II S4

Thanks,
Mike
