Unstable RPM

[CatBehemoth]

Sorry if it was discussed here already.
I am now in a middle of a trip and while riding/parking around Yellowstone NP I've noticed first a loss of power, then unstable idle (low but jumping to 2000), sometimes no engine braking and jumpy ride at low speed. When speed is more than 50 mph (approximately) only loss of power remains.
Did anyone have the same issue?
I will try to get ASAP appointment with local mechanics but if not, I will have to just ride home - if it won't get worse.

Has it had the 2 wiring recalls done? It can cause weird things. I haven’t heard of it causing things that extreme though. Tabasco probly can help u

You don't mention the CEL, but have you tried checking for diagnostic codes?

Could be all manner of things obvs. I'm thinking maybe an air leak on the inlet side. Could be the just something simple like the rubber cap on the TB.

Luckily I found a shop that let me skip the line. Turned out the problem was with spark plugs ( don't remember when changed last time, but getting so bad so fast probably indicates bad gas). Thanks everyone, I'm back on the road!
