I have been having problems with the tachometer on my 97 max. It started working only on occassion and now has stopped all together. Does anybody have any ideas on how i can fix it??

 

I am not sure how to fix the tach. I am sure others with more knowledge will chime in. But if worse comes to worse you can get something like an Apexi rev/speed meter that taps into the RPM wire of your ecu and moniter it that way.

It also may have something to do with the sending unit.
