I have a few problems. First, my shifter shakes like carzy when im at idel, is that normal? On my tack i see that my needle shakes like crazy too, in the 500 rpm range? So i assume i have a bad idle. Can my intake cause this to happen b/c when i had the OEM one on i was fine. Also im not sure but maybe my idle can be causing this but my exhaust rattles off and on, and when i go out to look at it it is shaking like crazy. What the hell is going on here?

 

you could have a vaccum leak, or your filter could be clogged.

 

Well the filter was just cleaned by a shop, but who knows with car shops these days, lazy slackers. How could i check if it was maybe a vacum leak?
