I have a stock 1995 Altima with a five speed tranny. When I'm freeway driving with the A/C on, I get about 2-3 "poofs" or "farts" from the exhaust every 5 minutes or so. It's not quite a backfire and happens so quickly, it doesn't register on the tach. Anyone else familiar with this problem? I'm thinking about running mid grade gas for a few tanks to see if that fixes it. My other thought may be time for a tune up?
Thanks in advance!
