I drive to work in the morning about 20 miles and the code is not there. I drive home after work and after about 10 miles the cel comes and the P2098 code is stored. I had to put mid grade in the car about a week ago. Would this cause the problem?

Are you sure that is the correct code? It isn't on my list.

The code was retrieved from an Actron code reader. It has to do with the post cat to lean. It actually was on both sides. Codes 2098 and 2096.

If the engine is running lean, check for vacuum leaks on the engine.
