Another 'starting problem' thread: For the past few weeks my '02 Sprint RS takes several seconds to start after sitting for a few days. Once started, it runs a little rough before finally settling into an idle. After that it runs fine, and it will start fine after a short break. But give it a day of rest and the starting issue is there again. I've checked the spark plugs, air filter, hoses to the air box. I'm thinking it could be a throttle body sync issue, but the fact that it runs fine once it up and going has me scratching my head. What are your thoughts?
