On my 99 ls1 i recently installed a new clutch. Ever sence if i leave my car set for a couple hours or over night and than i start it up the computer seams to reset. The spedo and tach peg out to 155mph ans 7grand. My trip odometer also resets which makes it hard to tell how long i have left on the clutch break in. Could it be that i left a sensor unpluged or something?
thanks, Dane
