Need some guidance on throttle/rpm problem.
I started having throttle issues about 2 months ago, on my 2014 Street Glide Special. It has 30,000 miles on it. At first, it was higher than normal RPM at idle, after being fully warmed up. I'd be sitting at a stop light, and the engine would jump to around 1400 RPM when it normally idles around 950-1050. It would do it for about 2-10 seconds and then come back down. I thought maybe it was the ECM just giving it some more fuel for whatever reason. Then, about two weeks ago, I noticed at a stop sign, I had to give it about 50% throttle to get any response in engine rpm. Didn't do it again until yesterday.
It only seems to do it when I pull the clutch in while shifting, or I'm at idle. I could understand the low end of my throttle being a little less sensitive, considering that's where I spend most of my throttle usage at? But I'm guessing the higher RPM could possibly be the same problem. Maybe consider remapping the ECM? Or do you guys think it's a TPS issue? I REALLY don't want to take my wiring out, considering how much of a pain it was to put in last year.
