[align=left]my tach is way off it claims that I am idling at 2500 rpm. Have any of you seen this before? How can I reset it? Would unplugging the battery for 30 min or so work? Please advise. Thanks

My tach is way off. It says I am idling at 2500rpm and at 70 I am turing 4200. Have any of you seen this before and if so how can I fix it. Would unplugging the battery oifr 30 min or so reset this? Please advise. Thanks!

are you certain that your engine ISNT turning those RPMs?

 

I had a problem with my Tach! Turned out the dealership had to replace my whole cluster! Warranty is AWESOME!!!

 

Wonder what model or year it is?
