Just bought a new 04 pace arrow. It has the 1000 transmission and 8.1 engine. When I have it in reverse and a little torque is required the engine trouble light comes on and a engine "low power message" is displayed. The engine acts as though it is runnung on maybe two cylinders or is being starved of fuel. You must turn off the engine and wait a few seconds and it will reset, however if you put it in reverse and apply a little torque it does it again. The dealer says they have never heard of this type of problem. I have only driven it home and have put approximately 40 miles on it. Any ideas.
