Hey guys,

When driving my check engine light sometimes comes on and stays on for about 10 minutes. I have no clue whats wrong, I was thinking the o2 sensors but i was hoping to get someone elses opinion.

Thanks

Its best to get the codes, since the CEL could be set off by any number of things. If you don't have a scanner, go to a Pep Boys or an Autozone store, they can pull the codes for free.

They cant. they only have OBDII connectors..... at least hte ones around me havent been able to.. Every OBDI MFG has a different connector (nissan consult, GM TechII, etc)
