Another customer comes from a lube shop that also does state inspections where a tech school student doing the inspection relayed to him that he needed a catalytic converter since his car failed inspection for a P0420. He came to me. I replaced the stuck open thermostat, $105, problem solved.

I wish I had seen this before I took my son's 2002 in for a cat converter. I just got back with the car 10 minutes ago. It BETTER pass SI now that they did the work. They (Georgetown Subaru) told me it needed a few 20 mile cycles to reset the fault.
On the way home I realize he needs a new clutch and brake work.
Do you have your own shop? I'd like to contact you.
