We recently had quite a few mechanical repairs made to our 1994 Monaco Executive. We also had a Banks performance package installed, and a new full body paint job. All of this took months and months. When we picked up the motor coach, we only went a few blocks before we turned around because of a lack of power. When we arrived back at the repair shop, it was quickly determined that the clevis pin on the Pac brake had fallen out which closed the butterfly. The pin was replaced and we drove home. The drive home includes several low grades and the motor home still seemed to be low on power. It barely made it up a steep grade close to our house. A week later, we started to drive back to the repair shop. The motor home had problems climbing a slight incline out of our driveway. I noticed the cruise control was set to ON (I never use it), so I turned cruise control off and things seemed to improve. Near the repair shop, I was in stop-and-go traffic and got a â€œdo not shiftâ€ and the motor home would NOT move. Turning the engine off and restarting cleared the â€œdo not shiftâ€ and I was able to make it to the repair shop. I learned that the repair shop had failed to install the â€œotto mindâ€ which is part of the Banks Stinger. After correcting this oversight and confirming nothing was wrong with the turboâ€™s cartridge assembly, test drives showed that there was plenty of power. However, steep inclines are still a problem as is staring out on a slight incline (after not driving the RV for a few days). Currently there are two codes (25-11 & 13-13) that will not reset. Does anyone know what these codes mean or have any idea of what the problem might be?
