I'm pretty sure that particular engine was **** in general.My gf had a Mitsubishi Eclipse GT Spyder V6 and just changing out the spark plugs was a huge PITA that I never had the misfortune of experiencing in any 4cyl. I stand by my opinion that 6+ cylinders are not as mechanic-friendly as 4cyl's. Fewer cylinders = less time and money spent on maintenance/repair.
Was it the last gen of Eclipse?
