Turning off "service engine soon" light
I have a 1998 200sx. Iam trying to turn off my "service engine soon light" . And i read some other forums and they said reset the ecu. This is what i did: I turned my key to the "on" position, then i loosed the screw on my ecu, when i looked at the dash the "service engine soon" light was off, i tightened the screw back to original position and the light came back on. How come it didn't stay shut off??? Do i need to do something different?? I know nothing is wrong with my car, because the reason the light came on in the first place is because i forgot to reconnect my MAF sensor, after i was done working on my intake. thanks for any help.
