only happens at the idle's lowest point. i have sri, header, engine mount inserts and advance timing mod fyi. i also have a slightly modded stock exhaust so if this could be a leak, let me know.

kinda goes blup blup... blup... blup blup blup... blup blup and i can feel it through the dash, shifter and wheel. when th a/c compressor cycles on, it goes away. if i leave the a/c off and tap the gas gently, there's a obvious vibration initially that goes away once the revs climb only slightly.

during driving i notice nothing, this only happens when idling at the very lowest point.

any idea?
