The old girl is acting up. I've been getting an intermittent CEL with the above codes. They clear after a couple days and then will reappear often after a morning cold start. The past couple days I've noticed a slight studder/misfire when pulling out of a parking space though this clears after a couple seconds of acceleration.
She has 191K and I suspect worn valve stem seals as she burns a bit of oil and will shoot some smoke out the pipes after a hot start with a couple minutes sitting before start. No smoke on cold starts in the morning...
I'm thinking maybe I should change out the O2 sensors?
Any other thoughts?
