High Idle...

[Firefly]

I can't remember if we ever came up with a definitive answer to the occasional 'high idle' on an RS/GS ???

Mines been doing it quite a bit lately... if I re-boot the bike a few times it goes away... but otherwise it will idle at 3,500 - 5,000......


Anyone remember what we found on this awhile ago??

Not saying this is the problem,
My 08 Gs would do that way back when, Then the ECM Bit the dust.:dontknow:

I believe it was the first recall, that caused popping in those spyders with aftermarket exhausts, when someone mentioned the problem of the high idle was corrected. I thought it did correct the idle problem because my spyder stopped doing it. However, months later it started up again and still periodically does it. It's annoying when it does happen; but, I have never had the dealer look at it b/c it is intermittent. I can't remember if letting the clutch out slowly while braking (while at a light) drops the fast idle so that you can engage the clutch again; I have an SM5.

The short answer is, no one ever found the problem that I'm aware of.

Ooops, I just noticed, Scotty got me on this while I was making my first correction.

I never found the cause on Nancy's GS. Hers was pretty much cured after the "performance update", which cured the purge valve problems that were caused by the initial steering recall firmware update. Possibilities to look at include an intake air leak, vacuum leak, dirty throttle body, or sticking throttle body or linkage due to wear. These are not fun to chase. With your mods, the cause may be even less clear.

I will start from the battery: keep her fully charged nojoke

2012 model with barely over a thousand on it and it happens to mine. Not 3500-5000 rpm's but maybe 2000-2500. It is still is obvious, intermittent and it goes away on it's own. No way could it be battery, throttle body or anything else mentioned thus far.

I think it's just a feature. :doorag:

My wife Frenchies bike had this problem. We had lots of trouble with the HID headlights screwing with the computer. After the computer was replaced, we had no problems. Turned out her problem was defective computer from the start. She has a 2008 GS SM-5.

I know it's not a mechanical problem--- it is computer related as a reboot is the only thing that fixes it. Battery new last year--- always kept on tender. Could be HID interference I suppose. I would say it happens every 25 starts--- usually at a very I opportune time

Could be HID interference I suppose.

My spyder did it before HID install and still did it periodically after install. The last time it did it was last Sept. I did have the ECU replaced last Nov. 8 and I rode it for a month after that with no high idle; but, that is to short of a time to determine if that helped. The ECU was replaced b/c the scrolling message at start up used to appear after the spyder was started.

When my spyder goes into high idle, it takes itself out of high idle after a few stop lights.

Mine does the scroll thing sometimes too... but not very often.

I'm curious as to what the computer is doing to make it idle so high since it is not 'fly by wire' like the RT.

The most likely way for the computer to cause the malfunction would be via the EFI. I doubt it is pooling fuel, but that's a possibility. leaking/sticking injectors could do that, or a faulty signal to the injectors. It would also be possible to introduce a vacuum leak electronically, but you have removed your purge system, so that's remote. Faulty sensors could change the fuel mixture or make the computer think the throttle body is not closed. So could bad connections in the wiring, which introduced intermittent signals or added resistance. Faulty sensors can cause intermittent issues, too. There are so very many places to have to look for this kind of thing. Without any fault codes, it is like searching for a needle in a haystack. Two sensors that I would test first would be the throttle position sensor and the AAPTS. Beyond that maybe your O2 eliminator and/or Juice Box. Could even be a problem with the computer thinking you have done a cold restart, related to your occasional scrolling semi-reboot.

Clamp off or otherwise disable the evap system. If that cures it you've got your culprit. Free fix and doesn't hurt anything. If it does not fix your issue you've at least eliminated one possiblity. Again, free diagnosis and doesn't hurt anything.

His is already long gone.

Mine goes the other way every once in a while, it will drop the RPM's down to 1100-1200, then it goes back to normal.

That is typically an ignition problem...bad plug wire, fouled plug, bad coil, or wounded ECM.

Sorry, didn't see that.

You could pull 1 spark plug wire, or let the clutch drag in gear, that should lower your idle RPM! :roflblack: I'm full of great information tonight!

The problem with the high idle was i had installed the wrong type ballast with my HID's. have you done any recent electrical mods? If so, try working backwards to isaolate the problem.

Nope, nothing new. Gonna do a teardown this weekend and check some things.....been running the same HID's for a couple years now... dunno-- maybe a ballast going bad... every now and then one headlight doesn't light up right away... might just swap the ballasts out with some spares I have just to be sure.

I have that same problem. I have HID's in both the headlights and fog lights. When I have the fog light switched on at start up one of my main headlights won't light up. If I wait to turn on the fog lights after the spyder is running...no problem. I still haven't figured the reason behind this, so I make sure the switch is off before I shut it down. Mine has been doing this for 2 years now.
