By the way, this is not the first time I notice that. I have been observing a contrary situation in beginning of summer: after setting idle to ~1100rpm in early spring, it raised to above 1200rpm in the beginning of summer. This is a bit annoying, because you have to resync the TBs when adjusting BBSs.
This just happened to me for the second time.
I own an '04 1150 and notice that occasionally the idle drops off. Usually I adjust and re-sync but I've noticed that each time I do, and then later run Techron Concentrate in a 1 ounce per gallon dosage for one tank of fuel, the idle comes back up and then I have to re-sync again. You would think I would learn to run the Techron first!
Anyway try running some Techron Concentrate through your fuel system.
