Idle rough

Got a new problem that has crept up on our MH. Got out this past weekend with no problem at first. As I got to our campground and was trying to find a site, I noticed the engine seemed have a lope in it as it idled and was lurching the MH. If I gave it a little gas driving through the campground it ran fine. When I got it backed into a site and got out, it was definitely loping as it sat there idling. Is this anything to worry about?

With engine running spray wd40 on all rubber vacuum hoses if you hear a change in rpm you have found a damaged hose.

WOW you bought a 1999 MH and have never checked out the engine?
What about all the belts, hoses etc that are 15 years old. Probably a fuel filter in the area as well.

I've never had the doghouse off. Hopefully that's not too much trouble. Things are tight up there.

Easiest thing to do is first look for vacuum leaks. As hoses age they can crack or come loose.
