Do you know which codes are stored and can you try the IAC unplugged for me prior to your next response?
No problem. I am here every day starting at about 3 pm central.
Are you flooring it in drive or park. In park or neutral the rev limiter will shut down the injectors to prevent damaging the engine. How did you come out on unplugging the IAC and checking the codes?
Thanks for asking your question and letting me try to help you.
If your confused on why or how to rate me, let me know.
I'm only paid from the deposit you've made when you rate 3,4, or 5 stars.
Follow up/Reply as many times as needed before or after rating.
When you unplug the idle air control valve what is the idle speed in park?
Can you keep it running with throttle pressure. I am trying to determine if the IAC is causing the high idle concerns.
With the IAC unplugged and holding just enough throttle to keep it running when you plug the IAC back in does it jump right back up to 3000 rpms and stay there like your original question?
