rb20det having a little problem please help.

[nissans14rb]

hey guys..i just started up my rb20det for te first time. sounds good on idle, but when i try to rev it up it sounds like it wont pass 2000 rpms it pulses there even when the throtle is open all the way it wont go any higher, it sounds like air is going in and creating pressure cuz the longer it stays open the more pressure is released thru the BOV. is it like vaccum problem maybe wiring?

i hope u guys understood wat i meant lol

thanks

Sounds like your maf or tps is unplugged. Your car is in limp mode that is why it wont let it rev anymore.

Check your codes on your ecu.
