OK, I saw that WBO2 sensor in your post and was hopeful that there was a solution for those of us on leaded race fuel. Oh well, I consider replacing the WBO2 sensor as just part of the expense of racing.

OK new spark plugs (old ones were fouled as AndyF suggested), and fuel pulled down on the cells where it idles. Idle smoothed out and a quick plug check looks slightly black but probably from before I was able to pull fuel down at idle. Had to readjust IAC Position, but all seems to be well now. Time for some warmer weather so I can take it to the track and test overall response. I'll datalog at the track. Learn is set to come on at 2000 RPM and at 150°F CTS.Comment
