monday morning i fired the bike up for my usual jaunt to work, had a strangely high idle, returned to normal after a minute or two. the ride to work seemed fine though i wasn't paying much attention to the idle after that (stupid me). after work i fired it up and upon taking off the bike was coughing, sputtering, losing power all throughout the rpm range, pulled over a few miles down the road, blipped the throttle a few times and she stalled on me. hit the killswitch off and back on, it fired right up and rode fine last 5-10 miles of my ride. that evening i took it to the gym and back with seemingly no issues. tuesday morning ride to work. it didn't sound "right" but then at this point i may have been over analyzing everything. bike has been parked in the shop at work due to rain until this afternoon. started the bike and as i began to pull it around the shop it was acting like i was in 2nd gear. had to give it a lot of throttle to get her moving. check engine light came on for about 30 seconds then disappeared. checked for codes and got the P0505 "loss of idle speed control" anyone else have the same symptoms with this code? i checked the usual suspects (vacuum leaks, ecm connections, torqued intake/exhaust bolts) any other help is appreciated

V02 intake, fuelpak, and exhaust were installed 10k miles ago, no issues until this. my only other thought is that friday evening in traffic at ROT rally she got up to around 255 degrees.

 

any input?

 

I think its the iat sensor .
