I have a. 2007 America that has 30k on it and has run perfect til this week. It acts fine except once in awhile it quits then revs up with extra fuel. Is there a screen in the tank or fuel filter? The dealer has done all the service until now. Just wondered if junk can get in peacock. I notice some paint off where you put in gas nossle so maybe chips are floating around in gas. Any thoughts. I thought I may drain tank tomorrow.
