I've replaced my tps, iac, idle switch, ecu, biss screw, coolant temp sensor, and o ring cleaned the upper intake manifold, and throttle body. Boost leak shows good. EGR is blocked. no vac leaks i've checked, rechecked and tested the system with fog. the vac reads -20 pretty steady. car has a safc and wideband so i can tune it. however, my idle surges pretty badly when cold, once warm it calms down but is still pretty bad 800+ when cold 200+ when warm rpm surge. The car was stock when I got it, it surged then and continues to do so today after all new IC piping, exhaust, turbo, etc. Any help would be awesome
