[boost infested]

i just made it home. my car wasnt moving when i push the gas pedal down, it would bucks/jerks when i try to rev her up above 2000rpm. at one point i put the gas pedal to the floor and she would rev down like i was in neutral.........?!?!

put gas in your car.

is that the best description you can give?

[boost infested]

lol, i did check for gas. i have 1/2 tank.

sounds like a slipping clutch.

sounds like a slipping clutch.

wouldnt my rpm go up and the car not moving?

[boost infested]

i did some searching, i think my car was in limp mode.

[klattr1]

sorry, i missed the rpm going down part.

r u sure u did not blow a hose or something?

[boost infested]

nope, this morning was fine... it happened once before.

Post your setup.

Sounds to me like your MAF sensor took a dive. Unplug it and see if it acts the same way.

[boost infested]

i think it might be the emanage. i did reset the ecu by unplugging the battery.

ok problem came back! shes running super rich at idle - idles rough/all the plugs are black, wont rev pass 2500rpm(like a rev limiter). i unplug the maf and it didnt change the rough idle at all. i am thinking it the maf but i dont have another one to try.

[PMan_S13]

if you unplug the maf and it stays the same then that is your problem.

What maf are you using? I might be able to help you out on this one. Got a few extras laying around for the s13.

[boost infested]

stock maf, i do have another one but i have to wait til my brother gets off work first. he has a 92.

[boost infested]

the question is how did my maf go bad?

[daniel240]

yes im almost positive its a mafs problem. mine did the same thing when i had a bad mafs.

[boost infested]

well, i learn something new about this car today. checking codes with the ecu. code 12 - maf. after resetting the ecu, she is running fine now. but as soon as i bolt the ecu and the kick panel back i get the code 12 right back. if i drive the car with the ecu on the floor the its fine. must be a loose connection.

Sounds like it to me.. an unconnected maf signal wire is same problem as a bad maf; no metering.

Redo the maf signal wires and you should be set.
