well heres the deal, i'm stumped. my car ran fine as always but when i converted back from a map sensor to a 300zx mafs sensor it runs like ass and sounds like its camming hard. %90 positive its a blown mafs, but when i wired in the neo the same day i developed an electrical issue...something is bypassing the ignition switch and giving constant power to the ecu at all times. this NEVER happend before. also their were like two plugs that i didnt label and not sure what they plugged to. the only thing i can think of is when i wired in the mafs i may have A. crossed some other wires or B. completley wired the mafs wrong. i'm willing to pay cash for someone to wire in the single cam mafs/pigtail, check the surrounding wiring in that area, and wire in the afc neo and set it, and solve the electrical issues, as well as set timing, and lastly check all the vacum lines to make sure they're hooked up right. i'll also be there helping as well, its just i DONT know wiring. give me a call or pm. my name is tim and my number is 757-287-9689. btw its an sr20 (redtop) in a hatch 240. the car is located at the auto hobby shop on quantico and will be on a lift.

 

300ZX MAFS don't go bad, if it sounds like its cammed hard I prob made a mistake on one of the vacuum hoses.

 

wtf? my 300zx mafs went bad and it made my car ran like shit. i couldnt rev pass 3k.

 

joe thats the stupidest thing i've ever heard, besides the joe doesnt make mistakes. lol...GET PAUL

 

Your one of few I use to sell Z32 mafs on sr20forum like crazy I would get them from junk yards I prob went thru about 12-13 all of which were good, I have never seen one go bad(unless they were being maxed out beyond 500HP) but anything is possible.

 

haha hope u get this shit figured out, i got my constant power prob to go away but have no cluster now.

 

The 1st thing i would do is compleatly disconnect the NEO every wire .See if you still have the problem .If you do then remove the Z32 mafs if the problem is no longer there then reconnect the Neo . That why you have eliminated the wireing problem and your problem would be the Mafs . Thats the easiest way i could think of to help ya ...

 

or if it was dropped or some shit, i never ran the mafs before so i couldve gotten a bad one

 

Maybe if you can't figure out the wiring just buy a boomslang harness sure its like 215 bucks but its less of a headache.

 

thats a lie!! the one you sold me broke!
