davey I totally understand what you went through. I guess that the idle control unit and the throttle actuator are one of the most expensive parts to replace. my mechanic says thats its the ICU.
I will definately mention the throttle actuator. I guess hell test it.
my rough first month!!!
could someone explain in a few sentences the function of throttle actuator. Is this also called throttle motor?
