Very Rough Idle

[Jabbo]

I've searched the forums and found some issues but wanted to get any fresh ideas. I feel pretty confidant that it's going to be ethanol gas as I have experienced these problems in the past with most of my small engines (lawnmower, 4 wheeler, chain saw, outboards, etc.) I for the most part only use ethanol free or add Sea Foam to the gas if not. Can't say that for the Spyder as I have filled up with ethanol in the past. We have been having "normal" weather in Southeast Louisiana this winter, 80 degrees and sun one day-Rainy and 19 degrees the next and plenty of humidity.
It ran perfect 2 weeks ago. Cranked it up last weekend and it was spitting, sputtering and dying at idle. Throttle up to around 2000 and runs like a sewing machine. No check engine light or any other codes that I'm aware of. I added some Sea Foam to the tank yesterday and ran it a little while. No changes yet.
And BTW, I love farmers but they need to grow corn to eat not burn. Just my opinion.
Thanks in advance!!

Put fresh gas in it (ethanol Free) and take it out for a spin.

Quick Check?

Are you positive it firing on all three cylinders?:bdh:Sounds like when you speed up the engine it goes away

ETHANOL - GAS ??????

IMHO that would be the last thing I would guess as to the issue here...... You may gotten a tank of BAD gas but the Ethanol wasn't it...... Think about it ...... 85 % of Spyders are forced to use it because they have no choice. I have yet to hear that it was identified as the cause. The V-twins as they get older have had issues with the VACUUM HOSES but I haven't heard of this with the 1330 engine....... I agree with FRESH GAS , but I don't think it MUST be Ethy free.........Mike :thumbup:

Have to agree...

Mike...
:agree: there seems to be a manifold leak somewhere. Once you create more pressure it seals up and run fine..Let us know what you find..:thumbup:

I've heard there are problems with some vacuum lines

I've heard there are problems with some vacuum lines

That's been the story with the 998s; we haven't heard that about the 1330s... :dontknow:
