Code Trouble...
92,000 miles
Just replaced the opti (again) about 500 miles ago. Before doing this I was getting code 42.
Got the car fixed (or so I thought) and now i'm getting H42 and H62!!
When I start the car up the check engine light is on. I'll start driving and all is fine except for the light. Then after a while the light will go off. But again it will come back on. I tried to delete the codes and unplug the battery but the codes keep popping up. Any thoughts...
