HESITATION WHILE RIDING IN HOT WEATHER

[Questions]

I notice when Im running in warmer weather (mid to upper 80s) that I get a slight hesitation in the throttle when I take off and sometimes running at 55-60 range.I throttle up or down a little then it goes away. Would it be something simple like needing gas treatment ? I have a 2012 RT SM5. I don't notice it all the time, just in warmer weather.

Thanks in advance.

I don't have a solid answer.

Does the machine power sag or just hesitate?

What fuel brand and grade do you burn in the Spyder. You may consider two tanks of a quality fuel such as Chevron, Texaco, Mobil, Exxon or other major brand.

Also try running a couple of tanks of the best octane.

See if this makes a change.

Obvious things could be a fuel filter concern but that seems slim considering it is not a constant problem or happening under all acceleration events.

I know other here have had spark plug wire issues. You did not mention a misfire, but that can be a possibility.

If it were me, I would replace the intercylinder vacuum hose. If the engine is running stable, but borderline on account of a vacuum leak, any throttle change will feel lean, causing a hesitation and then the power may resume.

I don't have a link, however there are a lot of topics here about the hose replacement. I believe Finless Bob even did a video.
Seems the better solution is to replace the oem rubber hose with a high temp version made from silicone.

All the best with it.

I agree vaccum hoses cracked ,leaking ,it's time, use silicon hoses.
