I start my car, the tach goes to about 4750 rpm and stays there. Car runs fine. Before I start poking around, wanted to see if anyone has run across this same problemo. Thanks.

Stock tach?Originally Posted by gkeepa
If no other problems and you did not 'change' anything then its probably that you tach is dying.

Tach question
Yeah, it's stock. Any ideas about swap options/using guts for repair from another Fox-body tach/referrals to guage repairs shops any of you mighta used before? Thanks for any input.
Are you certain that the needle isnt mechanically binding on something? Im not familiar with that particular tach and I cannot say if you could swap 'the guts' from a Mustang tach or not. Im sure that LTD LX tach is RARE. Basically I think you need to (carefully) pull your instrument cluster and take out the tach and go from there.

No idea, but as mentioned, the tachs are hard to find. I believe the guts are different than other Ford tachs, but I have no proof to back that up.

'85 LTD LX Tach
I don't know if it's hanging up on anything, per se. When I turn off the car, it drops back down to Zero as it would normally, it's just dropping from
4500+ rpm instead of +/- 750 rpm. Right after I start the car, It'll shoot straight up with(seemingly) no snags/hesitation. I try to catch any needle movement while I'm driving--it does move a bit between 4500 and 5000, but it doesn't coincide with acceleration or deceleration. It's definitely a ponderous situation. As I find time to look into it, I'll keep you all posted as to any discoveries I make(good or not-so-good). Thanks for the input. I am not looking forward to the investigation process.
