83 Venture,, slow tach movement?

[cowpuc]

Got a question for those of you who know 1st Gen electronics.. Guy asked me today about an issue that just started with his 84 Venture.. Said his Tach has started responding real slow,, wanted to know if he should replace/lube the tach cable.. I was telling him that the tach was actually electronic and that,,, if I recall,, I had read that a "slow movement tach" could indicate ecm problems... Got thinking on the way home that I should ask the pros on here about it NOW so if I gotta call him and eat some crow the crow doesnt have time to spoil before I have to eat it...

What do think gang???

 

Thanks!!

Puc
