Dumpy little shop ... we thought we finally found someone who could fix the threading on our oxygen sensor for our van. The guy said he could fix it and to come back in a couple hours. He totally messed it up ... looked like he tried to re-make the threading by hand instead of using a die or something. The part cost $180, $25 for the repair (if that's what you call it) and now there's no way around it ... we have to buy another one.
