To make a long story short. My 01 Blazer wouldn't pass inspection for a check engine light being on. After taking it to two other shops who charged me for nothing, finish line got it right. The owner seemed a little cocky on the phone. However, within 3 hours of dropping my truck off, they called me to say it was done. $125 for diagnostic and repair. A broken oxygen sensor wire. I had already spent over $700 at pervious shops. Passed inspection with no problem. I would reccomend these guys to anyone.
