Hey guys. Changed my engine on my 300zx na for another na engine I was having trouble starting it because the injectors were clogged after I changed the injectors it started right up but as soon as it starts it revs up to like 2,500 rpms what might be causing this? I already checked the throttle cable and the tps was set to .45......the iac or iav valve the screw that you adjust idle with is more than half way in?thanks for your help
