OK I�ve got this weird problem.
My car, 99 SE Sport V6 MTX 67,000 miles, was running great, but the air cleaner is dirty (have a SVT air cleaner installed) and I�m due for a smog test. So I go buy a new (Fram) air cleaner and install it and my car starts running like crap, surging and sputtering while I'm driving. It was also idling really low and loopy while making the valve train clatter. I pulled the two fuses for a few minutes to reset the commuter and it still runs the same. I yanked out the new air cleaner & put the old one back in and it runs fine again. What�s up with that??????????????????????
ANY IDEAS?
