ever since i put a new fender mount CAI on my car its been idling like crap for the first 5 mins or so when warming up....it actually cuts off about 3 times b4 it will stay running.....also i the other day when i was gettin on it i looked back and it was throwing alot of white smoke out the back.....(this may also be b/c of the 170,000 miles on the car)....do i need to reset the computer or something so it will acknowleged the new CAI or what?
