i don't drive it very often lately i usually commute on my vespa or bicycle. i drive it maybe once every week or so and just for pretty short distances around town, like less than 10 miles for the most part. i drove it the other night and it behaved fine, but today it's been really groggy feeling. it's extremely humid and muggy today, i wonder if that has anything to do with it? it's was hesitant to start and then stalled a block down the road at a stop sign. it started again and ran pretty rough, but after revving it in neutral a couple times it seemed to clear up. it almost felt like it was clearing it's throat. any ideas what could be wrong with it? should i take it for a couple good 70 mph blasts on the interstate to try to clear it out?
