Well, im getting a P0422 code now. Cleared it out after making sure my gas cap was on good and it did me no good. Came back on today on the highway.

There seems to be a plethora of possibilities but im not sure where to get started. Is it possible overheating a couple weeks ago led to this?

PO422 = small evap leak detected. Have the EVAP system smoke checked.

Actually 422 is catylyst efficiency which could be a bad, or either o2 sensor, have it checked out.

OOOOOPPPS, How did I screw that up? Sorry!!
