Suggestions/opinions please-
A: find one here in a part out
B: junkyard
C: new from GregV for $80
D: new from eBay for $40 http://item.mobileweb.ebay.com/viewitem?itemId=281118521788

Thanks


Unless you want to throw away your money do not purchase one from ebay, i personaly have bought countless after market ones and none have made it past a few runs
your better off buying a used one

talking from experience ....

That's always one option. @erikalizzetalanis - maybe you should consider this to get around your MAF issues.



Right About now im thinking to just buy a stand alone unfortunately price is killer but for now im working on the new Manifold bought flanges and pipe yesterday

Edited my original post. The price I listed from GregV was my misunderstanding and incorrect.

K, I got some voltage readings from the pigtail but nothing from the MAF with ohms selected. I've never used the ohms setting before but a buddy said it sends a current to a source which doesn't have power. These are my pigtail readings, I imagine they're legit?

Volts: 11.98 <---key on engine not running
Pigtail-
E: 11.94
D: 10.9
C: 11.2
B: 18.8

Z32 91-96 MAF (Letter Below Can Be Seen On MAF) Please join C and D and now you are back to a 3 wire MAF setup.

A. Nothing goes here
B. 5 volt output read wire
C. Ground
D. Ground
E. 12 volt Positve
F. Nothing Goes here

Wiring the MAF is a part of the process I actually didn't do. My buddy who helped do the swap was the mastermind behind it. He took care of that while I attended to other items.

Reference point: car has always run just about flawlessly minus a recently cured idle issue and tuning. MAF always read proper voltage in realtime too up till now with 0.01%.

NOOOOOW going over his work I see one thing that may or may not be kosher. But seems legit. Either way I don't think it'd be messing with power readings like mine is doing.....unless my multi tool is whacked.

I have B and E wired correctly according to Andreas' info....it's my grounds I now question but again, I don't think grounds would mess with power unless crossed (obviously). Where its said to twist C + D together, it's not said where to connect them afterwards. I imagine it's to be assumed to twist and wire them into the harness....that's what I'd have done anyway. Seems my buddy decided to wire C to the chassis and D to the harness white wire. According to Andreas in that link, white is ground.

So yeah, @lynchfourtwenty, my numbers DEFINITELY don't make sense!!!! If not for anything else, especially C where it's wired directly to the chassis. Brand spanking new batteries in the multi-tool too.

my car hated the extra ground to the chassis, would not run for shite... my 2 cents
