i have a 91 might max. i took it to get smogged and it didnt pass. The light stays on, but when i took it to get smoged i took the light off. It passed all the test and was going to pass, untill the dude check it out again,He said everything was good but that the CHECK ENGIN light didnt turn off and then on when starting the truck. So my question is , what can be the problem if all the test past. Someone told me it could be the computer??? Anyone else got any ideas??
