Rough running - ZR-1 Net Registry Forums

I still have the slight backfire in the exhaust when coasting to a stop and in gear.

I had a few hesitations today when at a lower speed and going 25-50% throttle. It almost cut out. I do now have some datalogs. I'm not sure how to look at what is going on from the logs?

I noticed BLM when at part throttle are NEVER at 128. They are always at 125-112. That seems rich, but would O2 sensors affect this reading?
