MY cars idles right where it should around 14.5-15 AFR until the car warms up! After the car is fully warm the idle won't move from 12.5 I can add all the full or subtract all the fuel in the world but it does not change my idle AFR.
Could this be a Coolant temp sensor problem or is the ECU not going into open loop? Any ideas before I tear into it?
BTW it a SOHC KA-T
