Ok anybody has some input

[VNG704]

check MAFS, connection, wiring, ground....

lots of smoke when you rev? if so, probably vacuum leak ...check vacuum lines, intercooler piping/couplers.


have you tried the "search" button? this seems to be a popular problem.

MAF definetely.
pull codes from the ecu and make sure its not in limp mode.
if the red light stays on when u start the car and its running, its in limp mode

Check your coil pack ground wire, and vacuum routing. Don't use the old egr vacuum nipple for anything, cap it off. It's found underneath the TB plate.

ok so I was working on my car and i noticed i had a bent fuel rail and my injectors were not sitting properly and cathching air/ leaking air i gotts doeble check my ground on my coil packs but it seems fine, I am about to pick up a new fuel rail becuase the one i have is really bad, thanks for the input i will definately check everything out.

[s13coupe1988]

ok guys i changed my fuel rail and no luck yet i checked the voltage on my maf and it was
11.0 on the black and white cable and 1.6 on the white wire? what could be wrong? thanks

[lazysk8er2]

check all your sensors. something might be coming loose with vibration.

check intercooler piping and all vac leaks.

check grounds.

check the ecu ground and ecu itself.

[s13coupe1988]

hmm i dont remember seeing the ecu grounded, i checked all my vacuum lines and they seem just fine and im going to double check my vacuum lines and ic pipeing, but like i said before signal wire for the maf is only reading 1.6 what could it be? thanks for the help

[s13coupe1988]

Ok i just posted a vid i hope it helps thanks alot

[ddf2006]

i watched the video and forsure its a sensor i can tell u that. my guess is your mafs, because even though u checked the wires, doesnt mean the actuall sensor its self isnt broken.
this happined to my mafs and wen i unplugged it i wouldnt rev past 3k.
try this, while the car is running, unplug ur mafs and see if theres much of a difference.

[chituntang]

pull codes off ECU!!!!!!!!!!!!!
Easiest thing you could have done yourself!!!!!!!!!!!!!!!

And if it is a sensor problem, the easiest way to find out is to unplug them one by one.

[s13coupe1988]

ok will do but how can i tell after unpluging the maf if its bad?

unscrew the maf from the intake and make sure the sensors that are hit by air aren't covered in dirt.

make sure your 02 sensor isn't fouled out as well.

check your coil pack and maf wiring to make sure it's not grounding on the chassis anywhere.

ddf2006, I think it's the modding.
