Hello I have a 87 turbo With idle issues. I just had my car in for diagnostics and im not throwing any codes. What is happening is my idle bounces from 1000 to 1350. When I step on gas peddle car goes like im at open throttle. adjusted tps to 1 ohm but still bounces. Im lost please help I have safc 2 and r and p fuel cut defencer No cat or air pump. just put car together new to rotaries. any help would be appreciated thanks.

 

check for air leaks....i have the same problem right now after my engine swap. im gonna check and recheck all my hoses and then put a brand new gasket on my uim. then i'll think about messing with the tps, bac, and the idle screw. aslo do a search for "bouncing idle"
