High Idle RPM

[CanAmChris]

I have talked to the dealer and they say no one has reported this.

Sometimes when I come to a full or partial stop and the Spyder (SE-5) down shifts to first gear it will stay at around 1450 RPM but if I let off the brake it will lurch forward and if I don't hit the brake again it will rev up to 3000 RPM and I can shift into second gear without touching the trottle.

I can feel it wanting to go when this happens and if I put it in neutral it tachs up to 2800 RPM to 3000 RPM and very slowly revs down to 1450 or so.

Has anyone else experienced this?

Nancy had a similar problem. Pretty much went away after the ECM was reflashed. Still idles high occasionally, after hot restarts, but only to about 2 grand, and it drops quickly.

Sometimes with mine as well.

I also have an intermittent fast idling problem with my 08 SM5. Finally calms down after sitting for 5 seconds or so, like while sitting at a stoplight but might be idling high by the next stoplight. Gotta love it!!!

Same here. I don't believe it's happened again since the very first DPS recall/ECM reflash.

When I first purchased my Spyder, it had an erratic idle, turned out to be a very small crack in one of the vacuum lines, for what its worth...
