1995 Nissan Pathfinder Issues...Please HELP!

[rocky_mtn_a4]

Ok so a little background info first...Truck broke down on me coming home from work, turned out to be the rotor. Replaced it, truck started hiccuping around 2500 rpms...done the distributor cap, fuel filter, used EGR valve cleaned real well from the junk yard, a couple new vacuum lines, new coil wire...problem is it runs fine when its cold, but once it warms up it starts running like crap anything above idle. Idle's fine, just once you hit 2500 rpms it starts bouncing the tach around and smells like gas profusely. If you lay on the throttle heavily while its hiccuping, it'll backfire loud as heck out of the airbox...any advice? Please and thank you.

Not sure about the pathfinder, but other VG30s tend to have issues around 2500 when the MAF fails. Its pretty simple to test it with some jumpers and a meter.

Care to tell me the procedure? I'm replacing the fuel pump I'm pretty sure. Although I'd love to test that MAFS...They went out and bought a fuel pump because a tech at a local shop told em their pressure was 40% below normal. Here's that shops findings...
