stil haven't got the bin burned but i'm starting to think it's really the maf. at low speeds SOMETIMES it starts bucking. annoyying as hell. i drive mostly highway but when i put-put around town at low speeds i notice it more.

I think i need the bin but the maf is going all the way out too?

so anyone reading this remember that. i did that to try and find why when i touched the harness the idle changed. I didn't find the broken wire where i touched it. so i put it back together. today i noticed it does it again. so i think i need to go looking in the harness again.

Yeh sounds like maybe you've got an issue compounding the problem, it certainly shouldn't be that hard to drive at low rpm/low throttle. Hopefully you can get it sorted out.

that's what i think too. gonna have to pull that part of the harness atleast and check each wire. that's gonna suck. the idle only changes when i touch the wires on the engine bay side of the firewall. i can move the ecu and tug on the wires on the cabin side and have no change. ugh.

well i pulled the whole harness out and couldn't find the bad spot got really close though idk when you touch the harness it doesn't do it any more though

but i did find a thread on skylines about the maf being repaired. tried that as i'm still waiting on my new tune to come in. seemed like it helped. here is the info:

long story short you may be able to fix your n60 n62 z32 and so on mafs instead of buying a new one.

edit: idle just tanked back to 11.5 again . oh well it was worth a try. need to get my tune!!!!!!!!!!

Edit!!!!! this did Work! The car has no more bucking at low throttle or anything! and i tried a bin with the maf enrichment trigger lower and that took away the rich idle condition! Now i just need to figure out why the bin i'm using for lower enrichment trigger is so lean.
