1 /5 Federico Perez: Took my truck for a check engine light on , the mechanic scanned twice, he said 3 sensor needed replacement, $500 parts, $320 labor, drove my truck for 15 miles and check engine light came back again, took it back next day, he said I have to spend more money because it could be 3 other problems with it. Looks like he is just guessing the problem, I won’t recommend this mechanic at all.
