GREAT service; fast diagnostic and friendly people.
I was in town on vacation when my check engine light came on. I called on Saturday morning at 10am and they said to bring it in for a free diagnostic. I arrived at 11am, and by 1130 they had diagnosed a fuel mixture error, probably caused by crap gas I purchased at a truck stop. They reset the error code, clearing the check engine light.
I paid with only a handshake and a sincere thank you, since it was just a diagnostic on the engine light. Las Vegas Cadillac quoted me $125 to diagnose it, so yay for Aamco's free service.
I've filled up twice since the visit and the error light has not happened again.
Thanks guys! Hopefully the positive yelp will offset my free diagnostic.
