I took my car in to get a smog check. It was running fine. The car passed, no problem. When I drove away I noticed the idle was high. I finally took it to my mechanic. A small hole had been punched, not worn, in a vacuum line . They had punched the hole where it couldn't be seen until the part was taken out. No one other than the smog tech had access under the hood of my car. Coincidence. NOT! DO NOT TAKE YOUR CAR HERE. If you have had problems as I did, report them to the Bureau of Automotive Repair.
Cons: They'll try to rip you off
