Tach works sort of

My tach has gone to not really working very well. It reads idle speed going down the highway. Is that more than likely the sensor or something else?

quite often it's the sensor on top of the IP gear cover. Check it for cracked wires/missing insulation right at the sensor - common failure. If it's oily and the wires are cracked/missing insulation the inside of the sensor is likely damaged.

Yeah, 99% of the time the sensor is the problem.

Ditto everyone else. I had the same thing happen on my old truck and a new sensor cured it.

Not really, you'll have to get it from a ford stealership for about 80-90 bucks.

I called the local dealer yesterday and they said it would be $69. Seems a bit ridiculous. I may call International today just for grins. Sometimes they are quite a bit cheaper than Ford,
