I know im a new memeber here but i do know what im talking about i just need a little insight i recently just dropped a jdm vg30dett in my z it had 20,000 miles cleaned it up real good and dropped it in. well its running like shit at idle iratic as well up and down runs really rich and sounds as if its missing the injectors are good and properly installed, brand new harness as well all the unecessary crap is gone too egr, plenum coolant lines the damn carb canister ect, i noticed that the ptu harness i had was brittle so i made another one no diff occured i did notice that the pink wire on the subharness is the no.1 cyl so when i was doing my timing i noticed that it seemed to have lapses or intermitant signal at the no.1 cyl plug but perfect on the subharness before the ptu i set the timing belt and adjust the cas 3 seperated times all dead on no diff so as of right now i suspect the ptu but i dont wanna buy a new one if i dont have to lol so if anyone can help me that would be great
