Hello, Ive got a problem with a USDM 85 AW11. The car doesnt seem to idle when cold. it hunts when hot. it was like this after timing belt replacement, I confirmed the timing was correct. I can keep the car running by blipping the throttle when cold. but it then chokes at around 500-600rpm. when its hot its hunting around 800, the shop replaced the afm, tps, coolant temp sensor, the auxiliary air valve is working properly. Ignition timing is correct. Im stumped guys.
