Pontiac Problems? Ask a Mechanic for Answers ASAP
good evening my name is ***** ***** I will assist
the computer does its own test on the system and when it passes, it will set the monitor.
the monitor runs on cold start or when it has a cold soak for about 8 hours. the engine needs to run until warm and driven on the highway at 55 mph for about 3 minutes at a constant speed. the motor cannot be turned off and re started during this process or the test will stop and you will need another cold soak to re run
how are you making out??
please dont forget to rate me as it is the only way I get paid for my efforts
