I have a 2006 f250 6.0 and for some reason the tach gauge will not read right some times. The first time was about 7 months ago right before my oil cooler went south on me so I assumed it was related some how. I got all of the work done and it didn't do it again until last night. Going down the highway at 75 and its reading 1000 and slowly dropping even as I maintained speed. I could accelerate and it would move up but not to where it should be. After I exited and stopped at the first light it fixed it self?!?!?!?!WTF Is this a symptom of a bigger issue, or just a bad cluster/sensor ?
