Engine wont' idle under 2,000 rpm
When I first start my car up, it idles fine. But, after driving for a bit, it idles around 2,000 rpm and does not kick back down to normal. Nothing mechanical seems to be wrong, such as my cable being in a bind or the butterfly valve being stuck open. Could something be wrong with my IAB? Give me your thoughts.
