Rich & Rough Idle

My 09 has developed a rich & rough idle. I started with all the obvious areas, plugs, air filter, checked the intake seals for leaks... Nice to get the service items done but no change. I have searched this site & online but not found much that I have not already tried. I pulled the Temperature Manifold Absolute Pressure Sensor and cleaned that. The bike cold starts well - runs fine on the road - just the hot idle is the problem. I changed the cylinder head temp sensor - no change. The cleaning of the Temperature Manifold Absolute Pressure Sensor gave me a short lived smooth clean idle - then back rich & rough.

I have read where these MAPS never go bad yet everything points to this on my bike. I don't what to keep throwing parts at this hoping to find the culprit. Any thoughts or advise would be greatly appreciated.

Thanks, Rusty
