Thread: Vvl won't rev pass 3k¿????

So i just finish building my Nx built Vvl,,,,standing still the motor revs just fine but when in gear I can't rev pass 3k the car will shut off wont have any throttle respond till the rev drops like if the maf was bad so I swapped mafs 4 times 2N60 and regular De maf and still has the same problem I also have a safc and I took it off still has the same problem my wideband reads 22.2 lean so I check my FPR at 3k and I still have pressure also have a regular De ecu and chipped Vvl ecu I try both and the car still acts the same ((. hope someone could help me

You check your tps?

How did you check you fuel pressure? You are supposed to idle the engine and remove the vacuum line. I'm with redline though, sounds like your tps
