I installed a stock Jake Brake, purchased from my local dealer. I worked perfectly for a few month, but lately it will not engage eradictly, mostly after several hours into a trip. I suspect that some is a foul with the throttle position, as when the unit is working only the slightest depression of the excellarator will disengage it.
