I have an 07 FLHRC, screaming eagle slip ons with fin, digitally mapped, breather. At 42,000 miles it started stalling out at stops after 1/2 hr rides fires right back up, but annoying as heck. yeah heck. Dealer tells me it's my fuel filter needs changing, I did that and now I notice you refer to a tt410. could I get that please.

I did the TT410 quite a while ago (about 2 months and 3k miles) and haven't had the problem creep up since. Not to say you might not have an IAC valve problem or a bad TPS, but the factory recognized the early ECM programming was flawed for idle and came up with this flash download as their solution.

Hey ICLICK,bringing bike to be looked at Saturday.I will bring a copy of the TT410 since they do not know what I am talking about.But should I mention the IAC motor or will they be able to bring up some codes.I just want this fixed. Thx

I'm not sure how high- and low-idle issues relate, but most here seem to have the low-idle problems. I was the exception and low-idle stumble (never stalled) occurred only a few times in the year I had trouble with the cold-start high-idle. Also, how the SE AC breather mechanism plays into this is a mystery, but some think channeling the breather blow-by into the throttle body may be contributing to the idle issues by clogging the IAC motor in some way. I know that when I cleaned the orifice a bunch of dark, gunky-looking stuff came out with the carb cleaner. It could also be that cleaning the IAC orifice periodically might help.

Thanks for being here!!! re: idle high and low
Man I am glad to read all this from you folks. I purchased an 07 FLHTCUI the end of May with only 13k miles. Well I am sitting in a hotel in KC, MO returning to FL, been on the road since July 1. Rode to the Black Hills, so far have clocked over 5k miles on this trip and I had the bike in the shop 2 times in Rapid City for both problems. pull the clutch in and it dies, notice popping and rough ilde if it does idle. Hard starting once in a while, mostly starts up and dies. Let it sit for awhile and it may run fine. Sometimes it will start up and rev high up to 2k or 3k on the tach and then work its way back down and will idle then. It never sticks at high idle. The harley shop charged me 158 bucks and only changed the voltage gauge as it was showing overcharging at 16v most the time. Well here I am in KC and still in the same boat. Thanks for the TT now I downloaded it and will take it back to the local dealer when I get back to FL. This is driving me nuts. I know in the am it will work fine, then all of a sudden I will stop for gas and it will act up. I thought it was bad gas. Oh, took it to the HD dealer before I left SD and they could find nothing and wanted another 30+ bucks for diagnostic fees. I got upset and told them you didn't diagnose anything and I paid you for not fixing it before. So they threw that bill away. WHEW!! Thanks I will let you know what happens. Shouldn't the Harley shop know these problems exist?
Good Grief!! 1,300 miles to go to nurse it home and get it fixed I hope!

Well, brought bike in Sat. with the TT-410 with me.They tested th IAC,Temp sensor, looked at my fuel mgt and found nothing.So I am rite back to where I started. It isn't throwing any codes so no way of checking. Of course it will not do it while I am there,so I guess I will have to hope it will go away..not.

Another possible solution. There's a known issue of pressure build-up in the fuel lines - namely at the quick disconnect. Push up on the chrome ring and down on the fuel line to disconnect. Reconnect by pushing back in until it's captured. If it is pressure build-up, it should fire right up and the line in the tank will eventually need to be replaced.
If not - it was easy to do.
Good luck.

I have a stock '07 with ~24000 miles that has had intermittent low and high idle problems. They have always occurred after I've been riding for an hour or more and never during cold starts.
I first started having high idle issues. Occasionally, when I came to a stop, the engine would "idle" as high as 2500 rpm! Blipping the throttle wouldn't help and it would at times only increase the "idle rpm". Shutting it down (I use the kill switch, then the ignition switch) and restarting wouldn't get the rpm to decrease. The only way to get it to idle at 1000 rpm was to load the engine by dragging the clutch to get the rpm down and it would stay down until I gassed it again. When it was going through one of these spells, shutting it down for 20 minutes or so would cure it but the high idle rpm would come back within a half hour of getting back on the road. Before TT-410 came out, the dealer was trying to convince me (and himself) that it was due to sticking throttle cables even though the torque on the grip was always normal and the throttle always returned to the idle stop when the engine was acting up. I would go for months without a problem and then I go through a couple hours of this routine and then it would cure itself.
I have also had intermittent low idle issues. It would start fine cold and the idle would come down to 1000 rpm and life was good. After riding an hour or so, the engine would idle at around 800 rpm or less. With the low rpm problem, sometimes it would stall when I came to a stop. At other times, it would "catch itself" and not stall but I wish it had stalled because it sounded like crap when it did it. An early symptom of low idle problems was it would hunt slowly between 1K and 800 rpms. Once it started it would just dump to 800 rpm at a stop and either stall or stumble. Like with the high idle problem, it heals itself after an hour or two of riding.
When it is having a high or low rpm spell, I don't have a problem starting it. Gas mileage is consistently in the low to mid 40's mpg.
I brought TT-410 (Thanks I-Click!) with me when I put the bike up for storage last winter. The dealer went through the steps in the TT. Essentially all they did was update the ECM calibration and adjusted the throttle position sensor voltage to .57 VDC.
So far, I haven't had any problems. The problem is, in the past it will run like a top for months and then go through a couple frustrating hours of high idle of low idle and then run for months again without an issue.

UPDATE: The above earlier post was long and discussed both low and high issues I've had from time to time. I haven't had any problems at all this season so TT 410 solved my problems.
The day to day running has also improved. Gas mileage over the last ~1000 miles has improved to 44.9 mpg with mostly all two up riding (up from ~41 mpg). Also, it had an annoying, intermittent rpm surging when coming to a stop just before I was ready to pull in the clutch. It wasn't nasty; just a nuisance that would occur from time to time. Well, the "surging" has not recurred since the adjustments.
