Rough Idle, Check Engine then Limp Mode after Storage

[Chupaca]

from reading past history, most of the hoses failing are from those with the harsh climate changes and stored units. In those areas and conditions the silicone hoses would be a good idea. Really glad you found the problem and the advise given was helpful...

Where are these vacuum hoses located? Left or right side of bike? What Tupperware has to be removed to get to them?

thanks!

Left side Tupperware has to come off hoses located on left side of throttle body.

I'm going to check my vacuum lines for sure now!!

One other thing that is good preventive maintenance to do is to excersize electrical connectors and use dielectric grease to prevent corrosion.

For every electrical connector you can get to, separate the two halves and re insert them together 4 or 5 times. Then separate one more time, and put some dielectric grease in each of the female terminal recesses, then reinstall.

This saved me from a throttle body replacement that the dealer was instantly ready to do, when all it turned out to be was a corroded terminal. HAVE PUT TWO THOUSAND TROUBLE FREE MILES ON MY 2010 RTS SINCE THEN, so am pretty sure I didn't need a new throttle body!!

It's worth a try, IMHO.

Great information here.

I am having P1172 code, I guess it is the vacuum hoses (RT 2012).

I was able to get the back one out easy, having hard time with the front one since it is stuck pretty hard.

Any tricks how to get it out (heating, cutting....)

Thanks

I ended up cutting it off with razor knife.

Hi,

I replaced those two vacuum hoses took it for a 5 minutes ride but still getting the check engine and the P1172, bike is under warranty but dealer is 94 miles away (it will be a waste of two days for me and my wife).

Any ideas will be welcomed.

I got a 2012 RTS and got the P2279 code, changed out the hoses and all is well. It was a bit hard finding the front hose, removed the wire ties on the harness and was able to find it. My NAPA store only had the H458 and not the H466 silicone, so I replaced with the EPDM rubber this time. Will order the H466 for next year. Have to wonder why BRP doesn't use the silicone in the first place!!!
