1991 Maxima problems please help!!!!!!!!!!!!!!!!!!!!!!!

[jcthe1st]

I recently purchased a 91 Nissan Maxima V6 5spd and now I'm having some problems with it. On three (3) separate occasions, the car would not go above 1000, 2500, and 4000 rpms on acceleration. I replaced the fuel filter, rotor cap and button and now I'm stumped.

Is there anyone that has had a similar problem? I really want to keep the car because I know how reliable they are.

Here's a little info as to what happens when I tried to push the car past the rpms listed: backfires and acts as if the REV limiter is kicking in, but I don't know if this car has one.

The plugs were replaced on 9/7/08, rotor cap and button 9/6/08. I don't know what to check next. I'm an amateur mechanic and I'm stumped.

If anyone can help, I would really appreciate all the input. I bought that lovely Haynes manual and didn't help me out with this problem.

Check the MAF sensor. Air leaks on the trottle body side will cause similar problems. Also, if the MAF is bad it will cause this problem.
