I bought the car new in 2010 and from day 1 it has done this after a cold startup. If I drive with a steady light throttle it will buck two or three times before running normally. In addition, if I start the car while it's cold and let it run until it idles down the RPM will kick back up two or three times before settling down to a steady idle. I've tried the idle relearn called for in the owners manual several times and the car will idle and drive like it's supposed to for a few days before the condition starts to return. Three years ago I took it to the dealer twice for this and both times they said they didn't find anything wrong. Since then I've just been waiting for HPTuners to release support so I can try to figure it out for myself. Now that it's here I'd like to give it a shot. I'm just not sure where to look. Any suggestions? Is there anything I should look for with the 2.24 scanner?
