    RPM not stable on idle...!!!


    I changed my intake to APS 65mm CAI, I noticed the RPM is not stable when the car is on idle and the check engine sign was there as well. After that I installed back my OEM intake to see if it fix the problem, but it does not. The RPM still not stable and the check engine sign is there. I took the car to the dealer with the OEM installed, they only cleared the check engine sing but did not figure what is the problem. My RPM still not OK and the check engine sing is not there any more.

    Please help me how can I fix my RPM so it can run normal with the OEM intake.

    Check the MAF, and check for leaks. I take it the car is not displaying a CEL? Make sure the MAF is installed correctly (harness faces forward) and if so, gently -- gently wiggle the harness to see if intermittent contact will affect the idle (that is, whether the idle improves). Double check for leaks.
    The world breaks everyone and afterward many are strong in the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Ernest Hemingway, A Farewell to Arms, 1929
