The knock and crank codes could be due to the choppy idle from the crappy MAF. My MAF went bad last year and I was able to source a spare to try from a buddy with a 300zx, just to be certain after already seeing a code AND taking readings from a volt meter.

If you're neurotic like me and that MAF code isn't good enough to be certain, take readings with a volt meter to further pin point a MAF issue 👍

Sounds like your MAF is bad though, lol!

i gave wrong info about the MAF code, it only shows up when i unplug it lol but it doesn't idle right when i have it plugged in.

what maf and ecu do you have?

Hmm. Well I'd still start with checking the volts for each pin with a meter. Iirc, you should show 1.5, 12-14, and 0 for ground, on a z32 MAF. I could quite possibly be wrong. I figure things out as I go but unfortunately I don't often retain a lot of info such as this.

But yeah, what MAF are you running?

***EDIT: I just researched a bit to back myself up.....
The 5v wire should be around 1.0v at idle.
Power just like I said, 12-14v.
And ground is ground. Try re-grounding the MAF? Run another ground lead to the chassis.
Again, This info is all for a z32 MAF.

I have a Z32 MAF and JWT ECU 330cc Turbo.

Thank you 93specv for the quick responses and assistance!

At first I just looped my aicv regulator like you did and I had a very awesome idle that fluctuated between 1.5 and 3k, this was just on a N/A DE mind you. I have not really had the time to properly fix it so i put a toilet valve in line until I go to change my starter and everything else.

I think it's the turbo because there's blue smoke and then the MAF doesn't engage properly so I've narrowed it down to that.

lol swaps

I'd just swap that mess w/another car lol

regarding the blue smoke do you have the hose coming from the t of your valve cover going to the intake pipe that is connected to your turbo?
