Well it is starting to turn warm and I need to do some work the Ranger.

I need a good starting point on what could be causing my tach to jump from 900 RPM's to 2000 RPM's.

The tone of the engine doesn't change when this happens.

Also it will stay at 2000 RPM's then get higher as I drive and shift. It is almost like it is being fed wrong signals.

Need to know if I should check wiring in the dash, or check something in the engine compartment first. :icon_confused:

Specs:
1992 Ranger STX
4.0 ltr with Manuel trans
4x4 Auto Hubs

If you need any other information ask and I will get it for you.

Thanks for taking the time to help. :icon_thumby:

Daniel
