This past weekend I was driving my motorhome @ 55mph when it shuttered and the "check engine" light came on. It almost stalled, but I was able to keep it running to get home. (5 Miles) The oil level and trans. fluid was OK when I checked it. It is a 1997 Ford 460cu. in. Holiday Rambler. This is the 2nd time this happened, but when I start it again it seems to run fine. Any ideas what could be the problem? Or should I go straight to the Ford dealer & pay the big bucks? Funds are low so I'd really appreciate any help.
