Get yourself a few KA24E mafs from a junk yard. Actually just remove the maf sensor portion (leave the metal housing) you can pick up a few usually off any old S13s sitting around in various U-pull its. usually.

Try them all. You will have various luck but out of 3 usually 1 works really good.

Remembr, KA24E not DE the DOHC mafs wont work.

Don't really have any junk yards near by.. seems like the connector thats attached to the harness part wont snap Into place. . Very lose.. could I get these connectors at like auto zone?? And should I ask for a sohc maf right??

^^The MAFS sensor plug does not 'snap' into place. It's held in by a metal retainer (looks like a giant staple). You can get one from a Nissan dealer.... or a junk car... or make one out of bailing wire.

I see what u mean I dont have the wire that's in it. Maybe should wrap that sucker up with tape lol. Ima check my power source and see

[Mikester]

^^yep- do whatever you can do as a temporary measure to see if you can get the car to run... then do a permanent fix when you got it figured out.

[CalilayneSR20]

Awesome. Thanks guys. Worse case it is the maf .. could I go to like autozone and get one.. people are saying get the sohc maf instead of the dohc cause the one I have may be the dohc.. I jave a 91 240 chassis that had the ka24de in it

now sr20det

[Mikester]

^^no. You NEED either and SR20DET or KA24E MAFS. The DE MAFS will not work.

[CalilayneSR20]

Ok the ka24e maf I can just buy from a parts store?
Also the connectors u said nissan dealership will only have them

[Mikester]

Junk yard would have them, Nissan dealer... Very easy to home-make.

As far as the MAFS, do a Google search, Amazon.com, Ebay etc.
