I have a 2001 VW jetta (130,000 miles) and recently went to Midas to have my brake pads & rotors replaced. I have had a problem with the CEL coming on after I lost my gas cap.

He coated it w/ silicone to see if that would take care of the problem and the CEL was out for months. But,

2004 GMC Envoy, My service engine soon light came on. I took the vehicle to a mechanic and the code came back po422.

My check engine light in my 2003 Kia Rio keeps coming on. So far, my mechanic has pulled codes for and repaired the following. A flex hose pipe, the 02 sensor, pin holes in the exhaust, the gas tank and the purge solenoid. I am trying to get the vehicle inspected, but we can't seem to find the problem.

I have the code P0455 and P0442. I replaced the gas cap with a new cap and had a mechanic look underneath to see if their were any hoses off or leaks and he couldn't find any problem.
