Recently I rode my bike to a store, air temp was about 50*. As I started it to drive home, it idled extremely high. I shut it off, waited a minute and restarted it and got the same result. Finally on the third time it idled fine. Next day I took a cold weather ride. The temp was around 40*, as I would come up on a stoplight or sign the engine wanted to die. I've never had this before, but once back in the garage it idled fine. It is a 2011 Heritage Softail, fuel injected. Any ideas?

 

Wifes nightster had similar prob, but not necessarily in cold weather. Would also not drop revs sometimes when throttle off during normal riding. Fault was the Idle Air Control. Not seating correctly due to wear. Fitted new one and no more dramas.
Hope this helps. Pete

 

You have a bad TPS sensor.

 

Fast forward to the last couple of pages.

You figure it out yet?

 

I'm posting here because of the title.

My bike has is 6 weeks old but this idle "problem" has been going on since day one. It's all stock and when it's warm/hot, it idles at 900 to 1100 rpm. It's never a steady idle, like at 1000 and staying there. It's up and down, up and down. It doesn't even come close to doing the "potato, potato, potato" sound.

It hasn't been nice enough on a weekend to take it to the Harley shop, since I live so far from it, to see what they say what the problem is.

Any ideas? Or is it normal?

 

I dont know. I got to thinking about it and if the OP's bike is throttle by wire than there is no TPS. Is yours throttle by wire or cable. Have you checked for trouble codes?

 

Color me stupid but it's all stock, so I couldn't tell you anything about "trouble codes". I wouldn't know where to look or wouldn't know one, if it bit me on the butt. If you mean on that dash panel, where the clock/RPM/mileage is, nothing like a code shows there.

I've been away from bikes for 30+ years and so much has changed. If the weather would just clear up, I'd run it up to the Harley shop.

 

A red key light will stay lit if you had a code and when you need to read them there is a sticky here on how to read and clear codes. Do you have throttle cables?

 

I've never seen any red key light. And from what I know about new bikes, I can only guess I have cables. What else could it have? I do know it fuel injected, if that matters. Like I said, it's a stock Blackline.

It seems like I know squat about this bike and I agree. Sorry if I sound or seem like a dumbass. And Thanks for sticking with me on this.
