A common problem with sitting is water. Most gas additives will absorb this water in the tank.
I was watching from the waiting room when he first went to get the truck. He drove it around the lot to line up with the bay. I noticed he kinda stopped then must of pushed the pedal a little to hard and into the bush he went.Ok the tune could use a throttle adjustment sensitivity. But on a side note how fast was he trying to go in the parking lot? It’s takes a bit to get the throttle to do that you know this!
