Hey everyone! Back again with another problem, ive been having an ongoing engine light come on and off and now its stays on all the time. Sometimes affects my idle and other times, it runs very best, even with the light on. The codes are : 0 520267 5 & 1 520268 5, ive done some searching online and the two codes i have seem to point to iac stepper pin 1 & iac stepper pin 3 and both are "driver circuit open/grounded".
So i guess my question is, has anyone dealt with this problem? How and where do i find the "iac", and are their any tests i can do for the sensors? suppose another sensor is causing this? an adjustment ? any help will be appreciated!
