I was ripped off!.
James the mechanic told me he was going to clean out my mass air flow sensor. The bill was $95. When I took the car to another mechanic because it still would not pass smog it had to be recleaned. The air flow sensor had tons of dirt and crap in it and was never even removed to be cleaned. So I'm out the $95 for a non existent repair and the $60 for the smog test. When I went back to him, he gave me some bogus explanation. Do not go to this guy, he will rip you off if he thinks he can get away with it!
