Hi all-
I have recently noticed that my alty's idle will fluctuate 2-3 times up and down from around 800 to 2000 RPM. This only happens right after a warm start, and only lasts about 2 seconds. Never happens when cold starting, or when engine is warm and idling at a stoplight or something.... only right after you start the engine once it has already been warmed up (like after pumping gas).
I have seen this happen in a civic (but it was a lot more often and extensive) and it was a distributor problem. Any idea what it could be in the altima?
thanks-

Could be your TPS or maybe the MAF. I had that problem a while ago. On the passenger side of the engine, there is a small screw looking thing, the idle/air control..that might be off as well. My problem didnt stop, til just recently when I changed a fuel injector, now my ride is smooooooth
