Just got a call from my roommate, he's driving through Columbus, OH right now on his way to St. Louis. His check engine light keeps going on and off and when he "gives it gass, the engine stumbles". Thats all i could make out from him as his phone kept cutting in and out...Im guessing its hesitating to get into gear and drive, but its a manual???

Truck: '89 4Runner v6 Manual

Things he's done in the past week: SAS

IF YOU HAVE ANY SUGGESTION FOR HIM...PLEASE LET ME KNOW ASAP. He's already missed 2 days of classes getting the SAS done. Last thing he needs is to be stuck in the boonies of Ohio or IN for a week.
