Running rough?

[Kwalsh]

I have an 08 gs with 20k miles and it started running rough today and check engine light flickered and went off, is there normal maintenance I should do to it before I bring to dealer?
plugs?, valve adjustment? What's do at this mileage?

My 2010 RT did the same thing last year. I tried injector cleaner and fuel treatment but it ended up being the 2 small hoses from the MAP sensor to the tthrottle body. Couldn't see the cracks until they were pulled off. Replaced both hoses and ran like new.

My 2012 RTS is doing the same thing and is at the dealer. Will this show up on buds?

Did your check engine light come on?

If while it is running rough you press MODE-SET_TURNSIGNAL CANCEL all at once an error code or codes shows then it will show up in BUDDS, most likely a lean condition in one or both cylinders.

Mine did the same thing last year. After checking it out the two small lines had hair line cracks but I also changed to iridium plugs and the 8.8 mm wires as they were dried n looked cracked. But I'd check the two small lines first. I'm right up the hill on Middletown Rd if you need a hand or not sure were the two hoses are.

See this....


This is what it looks like..seemingly good

But they are drying out and start leaking. Good place to start looking :lecturef_smilie:

Yes, the engine light did come one. At one point I had to keep giving a little throttle at stops to keep it from dying.

Where do I find these hoses on the bike as my wife's 2011 RT is doing somewhat the same thing. Its running a bit rough and idling real high.

SILICON Hoses...highly rcommended

Rather than the OEM's....if dealer doesn't have...you buy and most dealers will install (that was my experience!!)....

 

[Chupaca]

They are under the left side panel upper area between the cylinder heads. There are two, use silicone 4mm hose cut to the same length to replace them. They last much longer...

Yes that was me and the wife coming back from Thatcher's park.

thats funny we were heading to her sisters camp just past thatcher park, great ride up that way and nice and cool.
let me look into my issues this week and hopefully an easy fix and we will have to get together for a ride

 

[Kwalsh]

Hoses are like bar and new, I pulled them off and checked for any cracks and none found so gonna do plugs and wires, probably going to order from Baja Ron as they are better and cheaper than Oem at dealer

 

[OJ UK]

My money's on plug wires (or HT leads as us Brits call them!)

Sounds like a plan. I can't ride in like weather today due to health problems. But yeah we'll get together for a ride soon. Good luck with the spyder.

I looked up on YouTube on how to access the throttle body on an RT. Do you really have to pull off all the front tupperware just to access those two rubber hoses that folks are telling me to check?

 

[Chupaca]

No..just the left side panel. Not sure how many panels on the RT but none of the front panels...

Good news one my running issue, plug wires were dry rotted and cracked, replaced wires and plugs with set from BajaRon and after a 45 mile test drive I can report that problem has been resolved and I am happy again.

a big thank you to BajaRon for having better parts cheaper and faster than local dealer
