2006 apex will not idle

[RTX]

Hey all just hoping to pick someones brain for some info.
I own a 2006 rtx with 4000 miles on it.
It had been running fine/never any issues. This past weekend when i came to a stop on the trail it stalled. I started it up and it would not run with out me giving it some gas/throttle.
It ran fine the whole way home (15 miles)as long as i didn't try to come to a complete stop, then it would stall.
I got it home and added dry gas in hopes that it might be bad fuel. it didn't help. My friends sled was running fine he also bought gas at the same place.

The next day I changed the plugs (they looked light brown and dry)and started it up.
It ran perfect because the engine was cold and the sled was in high idle/warm up mode. (red light on on the gauge cluster.) once the red light shut off i could hear the engine start to stumble but it kept running around 1800/2000 rpm. Once it kicked down to normal idle speed it would eventually (10 -15 seconds of running)stumble and die.
When it would start to stumble the yellow caution light along with the picture of a motor would start flashing on the gauge cluster. No other codes

I gave up and brought it to the dealer. They didn't look at it yet but said they had not experienced any issues like this yet. They said they thought the computer might need to be re-flashed.

Any one else experience anything like this?
anyone have any ideas on what it might be causing my problem?
Thanks in advance for any help
Steven

Maybe you got lucky and the idle adjustment screw just vibrated loose. There are two screws. One is the Idle air adjustment and the other is the regular idle adjustment.

If not that, I'd check oil level. I think it will flash when oil pressure is low. I doubt it is that because it would come on when cold.

Last but not least, do compression test. Mine wouldn't idle when I broke a piston but it would still run when I gave it a little throttle.

Please let us know what they found.

dealer called today and said the idle was 100 rpm low. they said they adjusted up 100 rpm and problem was solved. I think he said it should idle between 1600 and 1800 rpm. mine was at 1600.
I find it a little hard to believe that 100 rpm was causing the problem i was having but they seem pretty confident the issue is resolved.
He said the adjustment was made on the round black knob that is on the left side of the fuel injection.
i should be picking it up this weekend and riding it so i will know if it is resolved or not.

thanks for your reply

Sounds like your TPS sensor. Mine did the same thing and after one night in a heated garage solved the problem for a few hours and then it came back. If it happens again and you are getting terrible fuel mileage, it is your Throttle Position Sensor.

I believe the tps sensor cuz I have my idle SET INTENTIONALLY at 1350 without a problem

Yeah, that wasn't it. The yamaha IAC isn't that sensitive to have to be within 100 rpm. Hell, the idle will fluctuate more than that as conditions change !
You should always ask the dealer if they were able to "reproduce" your concern / trouble. If not, then how do they know they fixed it?

Prepare your self for disappointment when that gremlin shows back up at the worse possible time and makes you want to drive your sled thru your dealers showroom window!

Ya I know it isn't the idle rpm.
I am completely prepared to be disappointed when i pick up the sled.
This dealer came highly recomended. in fact i don't know anyone who had a bad experience with them.

My experience has been complete hell.
i told them of my problem with all the info anyone could need. they called me and told me they changed my engine oil and chaincase oil and did a full inspection on the sled. They said i also needed carbides and hyfax and wanted to know if i wanted them to install them. I said no to the hyfax and carbides.
I never asked for any of this service. all i wanted was the sled idle repaired. now i owe them 150.00 for oil and chaincase services i did not want or need and i know they did not resolve my issue.

My 07 RTX has started to see a similar inability to idle properly once in a while also.

I'm not seeing any codes yet and it has only stalled twice (so far).

In my case, when the problem is there it misfires a little at idle and just off idle. Everywhere else it runs flawlessly. Instead of idling smoothly at about 1600 rpm, it sometimes drops down to about 1000.

The strange thing is the problem completely goes away just as quickly as it flares up. Also there are never any codes, even after it stalls.

I've also only seen this problem after riding in extremely deep snow conditions, but I don't know if this is a coincidence. My airbox was definitely not filled with snow at least one time that it happened though.

Kyster, when your TPS went, was it imtermittent at all or did it just totally fail?

You dont owe them SQUAT..

sounds like they did you a free oil change..

They cant do work on your sled without your permission and then charge you for it.. Its against the law..

unless he signed the repair oder authorizing any work with and estimate numbered....at least thats how it is in mich.

Mine slowly went. It started with a little rumble when ever I came off the gas and then eventually it would stall every time I let off and let it idle down. It would only start if I gave it about quarter throttle. The more I rode it the worse It got. Eventually it would only run good when it was pinned. At WOT it was getting enough air to burn all the fuel it was getting. It also got horrible fuel mileage. I filled it up and I ran out in 59 miles on groomed trails. You will know when it is gone bad. This all happened within a day's ride.

I would not pay for a service that I DID NOT AUTHORIZE. If they do not have that on a RO that you signed then you are crazy if you pay for it.

 

[**sj**]

call the service mgr....then if no help...the mgr....if still no satisfaction...call yam cust svc!

No wonder that dealer is highly recommended. They are very thorough on looking over customers sleds to kindly inform them of work that needs to get done.
They must have just misunderstood you when you said "idle - problem" and they thought you said "oil and chain case lube change, look it over and find any possible thing wrong that you can charge me for - problem".
Honest mistake, they sound almost the same if you say it fast.

I am surprised they didn't just rebuild your engine for you...

Was it your TPS Switch? If not, you better check your compression. It sounds like you lost a cylinder.

Also, I found out that if you have any moisture and/or antifreeze in your oil it won't idle. The moisture evaporates and is "spit" out through your crankcase breather. It then is introduced into your airbox and wreaks havoc with the sled at idle. To check this, just unhook the hose hose that goes into the bottom of your airbox on the clutch side. If it idles better then you have moisture in your oil for some reason.
