172: HEGO HO2S sensor fault/lean
334: EGR Valve Voltage high
412: cannot control RPM during KOER high RPM check
531: invalid cylinder balance test due to throttle movement during test
632: overdrive transmission cancel switch/no action during self engine run test
All of the "popping", jerking, jumping, loss of power seems to start at about 2200 rpm. And then when the problem starts the Tach goes crazy - jumping all over the place. But the engine is not doing what the tach says.
So since the engine seemed to be doing okay, and it might still be 1-2 weeks before they will allow us back into our property, we take the motorhome to a very nice park about 25 miles away. The nice folks at this park were giving RVer's that were evacuating their RV's half off until they could move them again.
Anyway, about a week later, we decide to bring the motorhome home. Got her up and running and on cruise at about sixty five. Fifty miles down the road it starts throwing its fit again. We pull off and wait for twenty minutes. Start it up everything okay again. Another twenty miles down the road, same thing, only this time we had only waited about five minutes. So we waited another ten minutes and made the next twenty miles home. Although, it did hesitate very slightly a couple of times just before we drove in our driveway. It did not appear whether we waited a few minutes or twenty minutes after shutting it off.
The fuel pump was replaced with a "new" style at about 70,000 miles. New high end plugs and wires at about that same time. Changed distributor cap and rotor just before we brought it home this last drive. There is a 1997 Ford truck owners manual in the motorhome, but since it is set up for OBDI, it is most likely a 1996. The book says it is OBDII, but the engine in the motorhome is not. This is about to drive me nuts!
have the same problem?
