i have a 92 nx 2000, avenir motor, jim wolf ecu, 8.5 to 1 compression, 50 pound hr injectors, cobra maf. i had this setup running fine on a diffrent motor, but i replaced it with the one thats in there now. bought the motor from keo, had to install cams(had no trouble there, timing is set right), fired up the first time, but its only got 10 pounds of vacume, no matter what i try. i had install the intake manifold on to the avenir motor, ive checked the vacume lines on the back of the manifold over and over, pressure tested it, replaced the intake manifold gasket and throttle boddy gasket....and it STILL screwed up. idles rough like its got a heavy cam profile (it doesent) and runs like crap. its really rough, choppy, broken up before 3000 rpm.....it smoothes out abrumptly when you hit 3000, but its SLOW. i have no idea. ive tried EVERYTHING. i checked the maf, its fine. i even ran the maf blow through to see if it was a boost leak, nope. thats not the problem. maf is currently ON the throttle body, and its STILL 10 pounds of vacume, idles rough, has no power, EVEN when i put the gauge under the hood. no vacume leaks i can find......everything is nice and tight. what could possibly cause this? everythings the same, just a diffrent longblock i transfered my manifold and cams to. sensors? i dunno, i need help here. ive tried EVERYTHING.
