Tach going Nutty

[bgfire]

Hi everybody.

I am having trouble with my factory tach on my '93. Sometimes it registers, and sometimes it doesn't. It bounces a bunch.

Is the probably culprit the tach sending unit located in the timing gear cover? I noticed that one of the two wires appears to be loose right where the wire goes into the sender.

Is this a dealer only thing, or can I find it at Napa or Kragen?

Thanks a bunch in advance.

that's it. It's a dealer item, $50.

Yep, probably is the tack sender (located by the oil filler cap, get one from the stealership. Lucky you have a standard, if it was a auto the trans would be going into limp mode, hard, erratic shifts etc.

If the wires are loose thats likly the problem. BUT, you might want to try cleaning the unit first. Just take it out, use a little wd 40 or similar and a paper towel and put it back. It helped my tach a lot and it only took about 5 min.

Thanks for the help guys.

I figured it was probably the sender. I will check it before I get a new one, but it will probably be a trip to the stealership soon. [img]/ubbthreads/images/graemlins/frown.gif[/img]

When you get the new tach sensor in, tape the leads up so that it is stiff and zip-tie the leads to something solid. The wind from the cooling fan blows on the leads and we all know what happens to copper wire if it is bent back and forth a zillions times an hour. OkieGringo
