Gentlemen (& ladies ofcourse)
Last night I installed my new Gibson cat back exhaust and also my home made air intake system with a K&N and custom made polished aluminum tube.
Anyway, this morning while driving to work I realized that my idle Rpm is around 1300 now.
Is this normal due to the engine having to struggle less to take in air and get rid of it ?
If so how do I bring the idle back to 700 ?
Let me know please.
Thanks
