At the very end of our ride yesterday my sled would not idle or idle like crap. It would run fine when above 2500 rpms but would struggle at idle and give me a check engine light with code 13. I have the service manual and see that it is a bad air intake pressure sensor or bad connection but I thought I remember a recall on this sensor? Anybody remember hearing about bad 08 MTX intake air pressure sensor?

I just read something on here a few days ago that I think was related. Something about the wiring either coming undone or wearing through. You may check that.

Did not find anything. Found some people on Apexs who have them freeze up with moisture. Will have to tear this thing apart pretty far to get to them.

I seen that post but I seen on another post he found that some wires were mixed up on the install of the SC.
I guess I will take it apart and see what is going on. Maybe some wires rubbing or maybe a bad sensor. Will update as I go...

Fix this problem. Diagnostics mode works great and I highly suggest using it for any problem you may have with a sensor, INCLUDING T.O.R.S, but I found all my air pressure sensor within range of what they are supposed to be so it didn't help me but was still kinda neat. So I started taking things apart (seat, tank, spark plugs, steering post, air box, thorttle boddies, and moved wiring to get everything off) I found three problems it could:
1. Oil every where in the throttle bodies including some of the vent lines that went to the sensor. (from rolling sled over out west)
2. Main wiring harness was rubbing on the frame around the place where the service update was done.
3. Exhaust flex joint clamp on cylinder #3 was lying in the bottom of the heat shield, donut was still in good condition just the clamp fell off.
After fixing all three of these and replacing the spark plugs in starts up very easily and idles good. It is mostly something to do with all the oil in the throttle bodies, I cleaned my air box out after my west trip but it seems some must have gotten sucked in before I clean it.
