Update: I called my Acura dealer and told them what my car was doing and that I had heard of some issues they have had with the same problem on many cars. They offered to clean the egr system free. I took the car in and they kept it for a day. On the way home, the check engine light came back on. Same problem! I called them just after it came on. They said "bring it back". I took it back a few days later. This time they removed the intake and did a more thorough clean job of the egr ports. No charge! I thought it was pretty cool. Good service. Car runs much better and feels stronger now. Being going strong now for 2 weeks, no ses light.
