This has happened to me a couple of times now. As I pull off the exit ramp my bike starts to idle very slow, then it stalls. My bike is EFI and a recently replaced my throttle and idle cable. Possibly need to reset the throttle values on my Power Commander?

 

This is likely an issue with the IAC and is somewhat common on the 07 bike. There is a harley technical bulletin on this.

 

Gotta love a $3 fix. Thanks!

 

hey big e78 .my 07 roadglide will idle slow too, every once in a while also but it's never stalled. did you just buy a new iac or was it covered by the bulletin?

 

I haven't taken it in. I figured I try a $3 can of cleaner before I paid the $50 copay.

Someone tell me if I'm going about cleaning this correctly. On top, it looks like a round cylinder the circumference of a half dollar. On top of that sits a sensor. Do I spray cleaner around that sensor? There appears to be a port on the top of the inside of the induction module. Does this lead to the gunked up IAC? Can I squirt cleaner up this port?

 

big e, I've got an 07 Ultra that ran great few days ago, went to start next morning and wouldn't start..fired but wouldn't idle. I found one thread where someone said that if you open throttle part way and the bike starts, then the iac is good. Mine does start that way but dies when I let the throttle down. I'm still leaning towards the iac?....like to see the bulletin that FuelMoto is referring to. Nice if MOCO will fix out of warranty, but think I can tackle it if they won't. Haven't really seen anything else as to how to test the iac. I did spray clean inside the induction module at the iac, with rags stuffed towards the rear to keep any mess from going to the engine. Hope to hear more on this iac stuffs :-)

 

I couldn't find the bulletin either. I did spray carb cleaner inside my intake and making sure I sprayed it it really good in the port that leads to the IAC. No problems since doing that.

 

i had a simialar problem turned out to be the speedometer control modul it would idol low or die after a long hard run shut off and restart it would then run fine it also gave a intermitent check engine light but no codes.

 

Check out "TT-410: Big Twin Idle Improvements" dated August 3, 2009. It is specific to 2007 engine stalling and high idle problems.

I've had very sporadic spells (once or twice a year) of high idle and low idle/stalling issues with my '07. It's out of warranty but my dealer is trying to get pre-approval to update the ECM download and troubleshoot my bike in accordance with TT-410 at no cost to me.

 

What's TT-410?
