2007 Damon Daybreak, I have already changed oil, spark plugs, fuel filter, fuel pump and air filter. I run Sta-Bil in every tank and this just started happening 3 weeks ago which sparked me to start changing things after reading forums.

What do I do? After changing the fuel pump It is only reving up and down under NO load. When i turn the AC?s on it seems to level out.
 
It sounds like the idle circuit is partially blocked, try running Sea-Foam in the gas. If that doesn't clear it up you will have to tear into the carburetor and thoroughly clean it.
 
Thank you this is my plan for tomorrow if it doesn?t work i guess ill just replace it. Debating if I should go with OE parts or aftermarket carb?
