Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
Okay, the IAC may also be bad or in need of a re-learn.
I attached a procedure for you to follow and I also need to to drive it right away after you do this at idle and slow speeds, then idle again and turn on the AC.
This will train the IAC. if it doesn't work, check for vacuum leaks. If there are none, hen replace the IAC motor.
Hi, I'm just following up with you to see if you have any more questions.Thanks, Ron
Okay, I'll stay tuned in for you.
