Took my car to these guys to replace cracked flex pipe. When I picked up car my "check engine light" was on. They said that happens all the time. Took the car home, checked the O2 sensor with multimeter showed "faulty". Took the car back, they checked sensor, said it was faulty as well but it was not their fault and they would replace it if I paid for it. Took car back home and I replaced the sensor. I noticed old sensor was damaged. Sent them pictures, never heard back. DON'T RECOMMEND THEM !!!
