Hey
I would have searched but I have no cpu so any help is greatly appreciated. have a 96 g20 with a 99 motor the car won't rev past 2k rpm in any gear or neutral. It idles fine and drives fine under 2k. I think most likely its the distributor but wanted some thoughts from u guys so post up thanx a lot peace

Ok well I put in another distributor and same thing I unplugged the maf and the car did not shut off than I replugged it in and the car shut off.. I believe the car is suppose to automatically shut off? I than went to clear the check engine light which iturned on when I unplugged the maf. Than the car revved over 2k so maybe the car was in safe mode? The other code it threw was coolant temp I had 0 codes before all of this. Please post up any ideas or thoughts please thanx a lot peace

so the distributer didnt work?plz post if u fix it *** same thing happens to mine ill do the same

No it did not work. It started running right after I cleared the codes that I caused by unplugginh the maf. I fixed it but don't know what was originally wrong so regardless I want too figure out what's wrong.

well ive got three thing i got it down too its either my maf bad or bad ground um... bad o2 sensor.... or bad temp sensor.

HkSBlueBird4u · 07-12-2007, 03:41 PM

its the maf.... either bad ground or lose connection by the ecu..

also could be the ecu thats burnt

check the voltage at the maf at idle then WOT. once you either re-ground it or replace it. make sure you reset your ecu.

Blimpy · 07-12-2007, 05:49 PM

yeah what should the voltage be of the maf on idle what if its below or above the voltage?

JGG8891 · 07-12-2007, 05:52 PM

very good chance that it's the maf, same thing happened to me and it was that the maf was loose.

Mister Jew · 07-12-2007, 07:02 PM

well right now the car is running fine so i have no way to diagnose the problem now because it isnt doing it anymore.

what would cause the car to go into safe mode? a bad sensor is what i thought but i never got a check engine light so thats why i am confused.

Blimpy · 07-13-2007, 01:03 AM

it could be a loose sensor if it does it again try checking the sensors

HkSBlueBird4u · 07-13-2007, 04:08 PM

clean battery terminals?

punkrockprs · 08-11-2011, 01:14 AM

What sensor can it be? My cars doing the same
