yeah, that's a good point. By logic, it doesn't seem like only dirty gas and a dirty fuel filter could be causing a problem after only like 200 miles of driving after tune-ups. There must be something else, so a cruddy gas tank coupled with a bad fuel filter could be the culprit.

How would a guy figure out if his gas tank is nasty? And if it's nasty, how do I get it cleaned? Do you just drop the tank and hose the sucker out, or what?

Thanks!
