Speedometer & Tach Problems
#1
#5
The tach sensor is usually the culprit when the tach is malfunctioning. It's a dealer only part and will cost you $60-$80.
Do you have oversized tires? That will throw your speedometer off. I'm assuming this is on the 88 ford in your signature. The speedometer is still mechanically driven and the only way to correct it is to change the driven gear on the end of the speedometer cable.
