Likely a '90 and it's not unusual and will likely continue to get worse. There's DIY repairs for recalibration and I'm sure someone will provide some links and maybe personal experiences. I understand the requirements but have never personally done a fix.
I discovered mine when actually trying to confirm a rear axle ratio that would have explained my tach variance but this was on a car that wasn't thought to be modified. I checked mine vs. a Tech1 scanner rather than the C68 display. Mine is repaired and correct but NOT by me.
