have a 2000 motorhome that has a Ford 6.8 V10 engine. On my way back from New Orleans we started losing power. I can get up to 50 miles per hour and it starts to shake I can get it up to 60 and that's as fast as i can get then it just slips and shakes real bad. The only way I can increase speed above 60 is going downhill and tapping the gas pedal increase speed otherwise going uphill I start to lose speed and can't accelerate without slipping and a lot of vibration. With the scan tool it said I had misfires on cylinder 2, 7 + 8. All spark plugs were changed and cylinder coils. Cylinder 2 still shows misfire and the problem has not changed at first I thought it was a transmission but now I'm not so sure
