Thread: b14 maf headaches

its a 1996 b14 Se-r.

3 nights ago, my car was fine as i was driving home late, no sputters or hesitation just like usual. The next morning i go out to start it, starts fine, starts to idle funny, and when i pull out it skips, jerks, and sputters til it just died. turn it back on, idles for 30 seconds and dies again. sounded like hell btw.

first thing i did was check the maf. i unplug the maf to see how it runs in limp/safe mode. it ran like it should in limp mode. then, i plugged the maf back in, start it and it runs fine....

i drove it around the block a few times and after about 10 miles it starts missing again, progressively getting worse til i unplug, replug, and another 10 miles i go.

Someone please tell me what the hell my ECU is thinking.

also, the car has an safc2, could this be the issue maybe? id like to first try unplugging it and running the ecu straight from the maf. Is it difficult?

if the safc2 install is sloppy(i havent looked, but it probably is), will i have to get a new maf harness?

any links or info on how to test the b14 maf would be great. also, sorry if i sound like a newbie.

Had this problem with my maf before after switching to n62. Had some breaks in the wires on my pigtail that were right up against the connector.

yea i checked that already, since i had that happen before, had to limp it home. anyone have an ohmmeter i can borrow? lol

check out JIM WOLF TECHNOLOGY, INC. / NISSAN PERFORMANCE / NISSAN RACING /INFINITI PERFORMANCE Their tech section has instructions on wiring up a z32 maf, that may help you out. But from the sound of it, you have a loose connection somewhere, runs great one minute, bad the next. I'd look over my wiring really good as well as the safc.

alright thanks. the wiring looks like a birds nest next to the ecu thanks for the link!
