So my tachometer works on some rpm's at some times. some times it will idle perfectly at 800 in drive, and 1k at idle. but when you rev the engine, it doesn't go past 2k. then i tap on it, and it goes to 1500 at idle, 1100 in drive, and revs all the way into 6k. so... any ideas? corroded grounds is all i can think of. but where would they be? maybe follow the ground wire coming out of the tach? I think that something is corroded because i shouldn't be able to tap on the tach and have it move....
it just bugs the hell out of me. especially when climbing hills, and i look down, and i see my tach at 2k rpm. and think that my transmission is about to snap or something. but irreguardless, it has always made me worry a bit. not for my safety, but the condition of the truck.
