after installing ash 2.5 everthing, sp700, sz epprom, 740cc injectors, Wiring specialty harness.


ive set timing, tps, checked throttle bodies, boost leak check
data stream says the AAC is at 70% when usually its at 35-45% on most cars at idle. Through the eprom tables the ecu shows 53% at 85 degrees C, the im getting 70% in data stream?

i have fixed many idle and stall issues by setting timing, tps, idle speed adjustment screw correctly, but now matter now much i play with this car im only getting down to 1050 RPM minimum. im a little stumped. idle worked correctly before, engine was pulled and reinstalled, all terminals on idle valves are clean and in great shape. a Wiring specialty harness was installed and i had to correct two wires for the check engine light. Has anyone else had idle issues with a WS harness?


note car has HKS SSQV set up in recirculation
