Bad MAF? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So my car starts up fine when cold idling around 1000rpms. It runs fine at first then when the car gets warmed up it starts sputtering and when it starts sputtering I can't rev past 2000rpms in any gear. When this happened I limped the car home and turned it off for a minute and turned it back on and the car idled horribly, shifting from almost dying to about 1000rpms. While it was doing that I unplugged the MAF to see the car idle more consistently. So I was wondering if it's the MAF for certain? If so how does the car run fine until it gets warmed up?

Thanks in advance and Happy Thanksgiving.

Yeah. I don't really know any other s13 owners locally being that I'm a new owner myself. I do have a buddy out of state that said my car is going into a limp mode because of a bad MAF or wiring to the MAF. I was just wondering what other 240 owners thought.
