At least that is the only way I can really describe it. On my way to work this morning, my speedo and tach would drop and then resume normal operation. Now my tach has read inaccurately by up to 1000rpm for some time, but the speedo has never had problems until now. The odometer would even go out when the speedo needle fell for half a second or so. My only guess is that it could be bad wiring? Has anyone else had this problem?

 

happened to me once. bad alternator. check both battery and alternator.

 

Not that I don't believe you but I would welcome an explanation of how the alternator failing (essentially not charging the battery anymore) would cause your gauges to go out of wack.

 

Well I don't think it is the battery or alternator. My PFC is reading 13.8-14.3 volts consistently. But I guess it wouldn't hurt to get them checked.

 

its the acual cluster... someone did a write-up about it and at the end they acually took it apart and showed how to fix it! do quick search if you wanna save 300 bucks. if you dont i'll take your 300 bucks cause i have one for sale
