trojan6768 -> My RPM Tach is reading wrong. PLEASE HELP!!!! (8/3/2007 3:00:48 PM)
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!
