I've got a problem with my truck that is really getting me down. I tried taking it to a shop, but they told me that they have to see the problem in order for them to know how to fix it. And maybe that's true, but the problem only occurs sporadically. Let me see if I can adequately explain this.
If I take off too fast or stop too quickly & take off again, I run the risk of having my entire dashboard go out. My truck will still run and the radio, signals, and headlights still work. But the speedometer, odometer, gas gauge, heat gauge, etc... either goes straight down (the needle, that is)...or just freezes in its current position. The digital odometer either shows a mangled reading or no reading at all. If I continue to speed up when this occurs, estimating at about 55 miles an hour, my truck will start cutting out. It won't shut off, it'll just cut out. The gas pedal loses all pressure until I reach about 40 mph (again, I'm estimating since I don't know how fast I'm going at this point). Once I get around "40" again, the pressure comes back and I can accelerate a bit more. But, if I accelerate a little bit too much, I end up in the same situation (i.e., the gas pedal looses pressure and my truck cuts out). This is very embarrassing in traffic. And this cutting out can also occur if I take off too fast while my dashboard is experiencing its moment of dementia. It's as if the dashboard going out triggers my truck to start cutting out if I go over a certain speed.
I put a machine on it to see if I get any readings...and the only reading I get is a Knock Sensor malfunction. Now, could this be causing my problems?
I need some help, not a lecture in "Duh! The diagnostic machine says it's the Knock Sensor...so, change the Knock Sensor!" That may be the problem & I plan on doing that. But, I would just like to know if anyone has ever experienced this before and what did they do to solve the problem?
Any insight would be greatly appreciated!
Thanks guys.
