I have changed my fuel filter but when I get up to 2500 rpms my trucks starts spitting and sputtering bad and if I try to give it more gas completely loses power ? I was told it was my catylitic converter just wondering is ther anything else I could check other than this?
runs ok unless 2500 rpms or more on 1994 Nissan Pickup (D21)
Fuel Pump Pressure and flow rate
I HAVE HAD ALOT OF NISSAN HARDBODYS AND IT SOUNDS LIKE YOUR EGR VALVE REPLACE IT AND YOU SHOULD BE FINE. IT WILL FINALLY GET WERE IT WANT RUN AT ALL.
It may be your mass air flow sensor.
i have the exact same problem with my nissan, i removed the cat and checked the fuel pressure and i still have the problem, did you ever figure out what the problem was???
I had same problem and changed my coil and Bam good as new!
