loss of power
Greetings. I have a 2004 W Brave with an 8.1. This past May we stopped at a turnpike rest area to get gas. I restarted the RV and it did not want to stay running or move. I had it towed to a truck repair and they diagnosed the problem as a bad throttle-body. They replaced it and it ran great that afternoon and evening. The next day it ran good for an hour or so and then started loosing power and backfiring.
The fuel filter has been changed 3 times since January. The fuel pressure measures out at 14psi.
Yesterday trying to come across 68 from Hancock, MD to Morgantown, WV it gave us tons of problems. It would lose power going up the hills and seemed like when our speed would drop to around 30 mph, all of a sudden there would be a surge and it would start pulling again.
This continued the whole 104 miles we had to travel. We also noticed if we stopped, when it got really bad and was backfiring, shut the motor off and sit for 10 or 15 minutes, it would restart and run like nothing was wrong until we got up to speed and had to back off on the accelerator pedal.
Can anyone shed some good techanical knowledge? Thank you.
