Im reading off of my safc Carl H. Im getting really tired of this car. Im suppose to be ordering Nistune, bigger injectors, installing my hx40 onto my STEC manifold and running blow through all in the next 2-4 weeks and I can figure this mess out.....

It did this in the past but I have no clue how it fixed itself.. Like I was telling Chris.... the little tooth is in the cas sensor, Timing is spot on. And im having issues adjusting my idle?? again?? Seems that all this happened after my z32 maf install..

could it be my safc and my atmospheric bov?? It ran fine before the maf install??

Have you checked your TPS?

I'm having a similar problem too.

Can't get it to idle at a right speed and timing looks way off.

Runs crazy rich at idle.

Tried getting the idle down using the AAC, but couldn't.

If you figure out the problem, def post it up!!

Also make sure your NOT using that black loop off the ignitor wiring.

Rig up a spark plug wire or use the wire going directly to the coil.

Im using the middle wire on teh coil pack that fires cylinder #1. Im using a craftmans. I think that I will rig up a wasted spark plug wire and check that. My tps is in b/w 0.400-0.500 I just got finish looking over the fsm incase I missed something. I noticed on australiaskylines.com the dude that wrote up how to clean the aacv said to turn the screw on the comp all the way to the left and smidge to the right. well the fsm says turn it all the way ccw?? Just like some say you can adjust the idle with the tps pluged up...Im not sure about you and everyone else but when I disconnect the tps my idle jumps up about 200rpms or so?? I hate nissans...Imma go back honda!!
