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!

its a good idea to start with the cheap stuff first.....go with a tune-up, and move your way on up.

While I don't have a farting exhaust system, what would appear to be happening is every time the AC compressor engages, there is a sudden load on the engine and the car (probably on cruise control) compensates by goosing the throttle.
That, or your car needs to stop eating at White Castle...

Yeap had the same thing

I had the same thing happen on my just outta the box '98 alty.
It seemed to only happen to me when I pushed it real hard and the A/C was on. It would puff at about 4k rpm, slow for a sec, and then zoom back up to 6k and shift. Not sure how to fix it although a tune up never hurts : )

Yeah White Castle will do that.

mine does that if i come close to redline in 1st and 2nd gear if my a/c is set on like 3. i think its just letting out pressure. i thought it was normal

If yours farts, mine has constant diarrhea. I get that occurence when im driving under norm conditions. I feel it most commuting though on the freeway doing 70. Who has to stop eating at white castle, me ?
