I just responded to the link Eskimochaos has listed in his thread. Hope my response helps. I've had a couple of intermittent starts where it took a little longer than normal, but nothing even remotely persistent. Are you running high octane fuel? If you are, take a couple tanks of the cheap stuff and call me in the morning. As far as the odor goes, does it smell like sulfur/rotten eggs (attributed to the catalytic converters on the 4R's) or does it smell like gasoline. If it smells like gasoline, you might have a fuel leak which you should have fixed ASAP.
As for the seat pop/creak, I just started experiencing that a few months ago, I took it into the dealer and they performed a TSB on it (I don't have the TSB number unfortunately, sorry) but it still persisted. I WD-40 the heck out of the seat tracks and that kept the problem at bay for a while, but it is slowing sneaking back on me. I'm about a thousand miles away from my warranty expiring so I hope to get it resolved before then.
Best of luck and keep us posted.
Oh, and welcome.
