friday i took my car out it was running good and all but wen it got to like 70 degrees it started running a little rough felt like it was losing power and wen i parked it just stalled. so i took my cai off and drove it like that and it ran fine with nothing on the intake eccept if i let it drop under 1000 rpms it would stall then i put the cai on and it ran good but not as good as with no filter or when it was colder out any idea why it was running like ****

My guess would be a bad idle air valve or a bad tps my 93 gt was doing the same thing. I hope that fixed your problem.

Not too smart to run your car without an intake
