I have a 1994 Amigo that I have taken great care of. It’s been idling high and then occasionally drops very low. I have cleaned the throttle body and tried another mass air flow sensor. I don’t see anything that resembles an Idle Air Control valve on the throttle body. There is only a throttle position sensor, which I replaced with a factory part. Does anyone know if the 2.6L has one, and where it is located?
