Was told I needed to replace the idle air control valve and they would charge me $650 for the pleasure. Seemed ridiculously expensive so I called around and spoke to mechanics who said that was crazy, that it can be cleaned for $45 vs replacing it. When I called back and said I'd be picking up my car without them fixing it they were extremely rude and annoyed that I had done my research and found they were ripping me off. They didn't even admit that the valve can simply be cleaned! Charged me $130 for the diagnostic. AVOID AT ALL COSTS, COMPLETE RIP OFF.
