One thing I didnt mention was that the truck has been cranky to start. Once started it purrs fine. But it used to start right up. Truck has new plugs/wires/cap/distributor. The coil has not been replaced. But now when starting it cranks a good 4 to 5 seconds before starting.

I started noticing that around the same time the reverse issue popped up.
