Ed, you didn't have to get it done sooner. There's a reset button that clears the big CHECK ENGINE ENGINE ELECTRONICS message that covers the digital display items......it's the "R" button under the "H" & "M" buttons that you use to set the time. I just push that after I start the car and no more big message.... (there's still a little window box on the dash that holds the check engine display, but it doesn't bother me).
