Violent surging upon cold start????

[mkcoxn]

When I start my 1986 TR it surges for about 2-3 minutes until it warms up? The coolant temp sensor is within specs, ATS within specs, TPS is .44.

Also once the car is warmed up, When I shift to park the idle races very high, then it slowly comes down. In general it seems the idle is kind of high. I just replaced the IAC and no change.

The car is very slow to spool. But once it does it rips.

My setup: Reman engine with 10,000 miles, Walbro 255, FP hotwire, stock turbo, LT1 MAf with Translator, GN1 cold air intake, 42lb injectors, stock trans. Scanmaster. 115k southern car.
