Sticky Tach
 

Hey guys, just wondering if anyone else has had a problem along these lines. When I am driving the car the tach is fine up to 3000 rpm, however it will not go beyond that. When I really get on the gas it will only go to about 2000 rpm and will not go beyond. Thinking it may be a ground problem?

Also I have a pegged fuel gauge. Wondering if this is the same sort of thing, a ground or maybe a jammed float.

Any information or experiance anyone has on these issues is appriciated.

No problems here but maybe someone can help you. Hopefully it's a small issue

Man, I really hate electrical gremlins. Considering the fact your car was sitting dormant in that barn for a period of time, I think you're on the right track with the ground. Beyond that, I'm not much help, other than to say good luck.

Thanks guys, got the same kind of problem with a pegged fuel gauge too. Guess I'm just in for a lot of wire chasing and diagram reading.

If you need wiring diagrams let me know.

If ya got one that would be great. You around tomorrow?

Ohh man .... you owe me a beer for sure!

I've got 34 pages of the most detailed wiring diagrams that you've ever seen for your Mustang - direct from Ford. To boot they are in PDF format so you can open it right up on your computer!

P/M me your email address and I'll fire it off to you. (I don't know how to post a .pdf file on the forum. Once I figure out how, I'll post the .pdf's for all the years I have).

So ....... Is it fixed?
