I went to my dealer, explained the problem and fortunately had the bulletin printed out. Response, 4 week wait and they will have to do a battery of tests without my power commander plugged in before considering a flash. Why can't I just have them flash the damn thing. Why is this not a recall? I thought I had this problem licked when I replaced the breather valve hose and stopped using gas with ethanol. Then after about 3 weeks and a 4 day trip through Northern PA with no problems it resurfaced this weekend. GD IT!!!!

'07 Idle Issues
- Thread starter iThug
- Start date
Hi Jouuu,
Ok I have an 07 dyna which is out of warranty. Ive had this return to idle stalling for a while now, very intermittent and irritating also.
Ive cleaned the VSS and IAC, removed and checked the TPS, fitted an external breather with catch tank as I thought all the crap going into the intake was the problem messing up the IAC.Then found about TT410 and checked my TPS sensor volts which turned out to be only 0.47v.
I phoned the dealer and told him what was happening and what I had done, then that there was an ecu flash.I told him I had a PCV with autotune fitted ( dealers dont like PC)
and could he just flash with it fitted. To my surprise he said yes, no problem.
I even helped the tech at the dealers (he wasnt very knowledgable about fuel injection and nearly had a heart attack when he seen PCV and autotune under the seat.
Autotune uses the diagnostic port for power so all I had to do was unplug AT and plug in the HD digital technician.
He flashed the ECU from cal id 32900-07E to cal id 31856-08A he even printed out the sheet.
on the sheet it says "Non-Chargeable Calibration", I still had to pay for 0.5hrs labour.
it also says to use this cal on ECM no. 32852-08 or greater, 32534-05B or greater.
He then setup the TPS volts to 0.57v.
When I got home I connected the laptop for the PCV to reset the TPS and noticed that the IAC steps were low at 13 and you need Digital technician to adjust this, difficult to do as the autotune uses the diag port.
I just turned down the TPS sensor volts to 0.51v and the IAC steps are now 25 after warm up.
Bike is definately different, very smooth, sounds a little different as well.
No difference power wise.
Time will tell on the return to idle stalling.
Go to the dealer and tell them you just want the calibration upgrade flash, you dont need to take the PC off for him to run tests, why does he want to run tests ? At the end of the day you are the customer and he cant survive without them.
Regards,
Jeff

Which problem, high or low idle? Did you clean the IAT sensor? How did you do it while on the bike or did you remove it first?[/QUOTE
my bike would idle high and would stall when coming to a stop, with the bike off i removed air cleaner [ i have the se heavy breather ] opened the butterfly and put a rag in the throttle body then i gently sprayed the air idle sensor and the 1 thats recessed dont know what its called, removed rag waited a bit to let any cleaner dry up put it together fired it up and its been fine
Sorry to bring this thread up again folks, but I think I've solved my idle problems (at least for now). Using a solution described earlier in the thread, I used carb cleaner in the IAC port.
I tried spraying while the bike was running, but no go. Stalled imediately! I ended up just giving it a good spray while the engine was off, sprayed the butterfly, and everything else with any deposits on it, and held the throttle open for a minute to let some of the spray evaporate. Then started her up. Once it burned the cleaner out (5 seconds or so), the idle smoothed and she purred like a kitten.
I took her for a two hour ride and it was like riding a new bike. No idle issues whatsoever. I didn't realize how bad it was running!
I'm hoping this will just be an annual thing. i'm really not looking forward to replacing the IAC.
FWIW, I'm firmly convinced the idle issues are directly attributed to the oil spray on the IAC, and possibly the SE A/C's location of the crank vent tubes (with 07's only).
My thoughts on why this is "mostly" an 07 issue:
The longer stroke on then new 96 causes more oil spray to be drawn up into the intake, then the 88's short stroke crank. The problem doesn't seem to show itself until you upgrade the A/C which I'm assuming changes the airflow enough over stock to cause the oil spray to affect the IAC by coating it in oil.
Since HD redesigned the intake in 08, moving the IAC to a different location, the problem seems to have been eliminated in the newer models.
These things to me are the common denominators and the reason for the 07 enigma.
Anyway those are my results and thought's - hope it helps......

Your theory may very well be correct. The couple times I've had idle issues I've cleaned the IAC and throttle body throat and the problem goes away.

I've been having this same problem with mine.
I thought that it was the power commader V took it off and it was better but still acted up. I cleaned it up and it ran fine for a bit then started to act up again.
I asked Jamie at Fuelmoto and he said to replace the IAC. I think I'm going to do that and see if it stops.

I've had one high-idle episode in the month since replacing the IAC motor, and no low-idle issues. This one instance was mild, only about 1800 rpms after a warm start, and it returned to normal after a restart. If once a month is all I must endure I'm certainly not going to worry about it.
The PCV should have nothing to do with these idle issues unless the fuel values at idle have been set outside the norm.

I've been having the same problem with low idle problems on my 07 Deluxe. After a long ride at 60-70 mph, it will stallout at the first stop. Like a lot of others, this doesn't happen all the time and seems to reset itself after I restart the bike. I replaced the temp sensor and it made no difference. I cleaned out the the IAC valve, no difference. Today, the HD mechanic listened to the idle step motor as he switched the ignition on and said he heard a gear noise. He said that indicated I needed a new motor (approx $45). So I ordered the motor. It sounds like some of you also replaced that motor. Did it finally fix the problem? I know there can be lots of reasons for a poor idle, but I gotta believe the problem I'm having is the same as a lot of other guys are reporting, and they must have the same root cause. If it's the motor, then it's mechanical, if it's the map, then it's software.
Summer is almost here = )

I replaced mine last night and then tiook it for a ride. The time that I got to spend on the bike it seemed to idle good and didn't even think of stalling. I checked the idle speed with my laptop and the PCV program and it's 1050 rpms.
So far looks good more seat time will tell.
