240SX Problems

what type/style of AFC do you have? do you have it adjusted correctly? running too rich will foul plugs, but running too lean will cause pops, usually. also, is your TPS out of adjustment? I know on older nissans, you can adjust the tps within like a 15 degree range of motion.

if you have a good injector that you know is a 370 and a 550 take yours out and call midland diesel service they have injector cleaners and stuff, but they dont have a unit that calculates what they actually flow but they flow into a tube and you could see differances in amounts that came out. my dad works there talk to craig

well...it could be my maf but supposedly the car wont run if the maf is not plugged in right? If it is wired wrong changes are its sending weird signals if anything to the ECU...wait now that i think of it he had it unplugged when i got there and it was running and i actually drove it unplugged and he told me that it was unplugged later...we had to actually set up the AFC when we got to the car since it was set up wrong the first time so I know FOR SURE this time it has the right In and Out numbers...and all fuel is stock except for a 255HP pump...I have a SAFCII...on the way home and up until the other day it had been completely zero'd out so it was basically outta the system...i just recently took 5% off of the fuel from like 3k or so all the way up...yeah i was told it looks rich(black smoke and now fouled plugs) but smells lean so wtf does that mean? I did actually adjust my TPS and got the right .45v and 4.05v out of it...
The car came with bored out 550s in a box but im starting to wonder if he actually took em out or not...maybe i could compare the 2 and find out which ones are bigger etc...

bump...the car revs normally with the MAF unplugged...only supposed to rev to 2500...my IACV is completely unhooked so do i actually need it or not? Something with ECU or wiring...the harness was done by wiring specialties so it wasnt a homemade job...im thinkin it might be somethin with the AFC since im sure that was done himself...

Tony sounds like your due for a little bit of good luck.
