Throttle Actuator Trouble Codes - Help Please
2012 FLHTCU
52,000 miles
Stage 2 with PCV
Been having a bit of strange idling as of late - more noticeable when the bike is cold. It will fluctuate between 850 and 1000 RPM while idling once the engine speed drops from initial startup. Also, sitting at a stop and in 1st gear it seems like it takes more throttle to get going that normal - like it wants to lug unless I blip the throttle and get the RPMs up.
Today I pulled the air filter off and cleaned off the TMAP sensor inside the throttle body hoping that would help. No luck. Just returned from a 50 mile "test ride" and realized I have the PCV that I can look at codes with!! (The ride came in handy - gave me a chance to think about next steps!). Anyway, pulled the codes and found a P1511 and P2101 as shown in the picture.
A little research tells me it might have something to do with the TPS connection. Thoughts on that? Is the other pic the TPS connector? My service manual calls the device that connector plugs into a Throttle Control Actuator.
Any info would be great. Want to get this diagnosed and corrected because I leave soon on a bike trip from WI to CA. I don't need this acting up while I'm on the road.

the grip twist sensor in the bars plugs into a wire harness in the bars by the grip an then that one plugs into another connector in the fairing. I think I have a bad connection in the fairing since I relocated the connector to add an amp an replaced the bars so I removed an reconnected the connector. if I turn the bars to lock going left when parking it will trip the light. From everything I read the grip sensor had a "green plug" in the bars that deteriorates over time vibrating in the bars. I also hear it's rare for the grip sensor to fail just the connector goes bad so a lot of guys pull the sensor an hard wire the it to the harness.
There are 6 wires to connect, 2 sets of three but they are the same color just the wrap is different so watch that if you do it.

Pull that plug in the picture and clean the pins ,both male and female, with alcohol. Then put some dielectric gease in there. You should check the last few inches of those wires for any breaks or fraying too. If those wires check out ok I'd wrap the hell out of them with some electrical tape to try and eliminate some of the stress on the wires from that stupid sharp turn. Sad part is if the tps goes bad HD expects you to buy a whole new throttle body. That tps actually comes off with those metal clips so if you find a used throttle body for sale they can be swapped. Just an fyi you can pull codes using just your bike...the whole procedure and the description of the codes is,on the fuelmoto site...probably elsewhere too but that's where I go.

Cleared the codes this morning and pulled the connector to the TCA. Cleaned everything up the best I could with alcohol, checked the wires and taped them up good. Reassembled and started it up. Same issue but the codes haven't come back yet. RPMs jump around a couple hundred either direction. Once it gets warmed up it almost sounds like it misses every once in a while. Kind of stutters a bit but keeps on going. Give it some throttle and hold it there and it purrs like a kitten. Now what?

So, I found this based on reading my service manual... the picture is of the purge tube fitting on top of the intake. Should there be a rubber cap on it?? If I start the bike and put my finger over it the bike stumbles like it's going to quit and then recovers and seems to run OK without the RPMs jumping around as much.
