A funny thing happened on the way home from the grocery store. Our rover started sputtering but only under certain conditions. Motor will idle fine and when gas peddle is pressed will rev up fine too. The problem comes when engine is under a load. It is very hard to get moving due to sputtering and stalling, but once it is moving it seems to do ok at a steady speed. but upon accelerating it sputters again, and does the same thing up small hills as well. So far we have added fuel additive, dropped the tank to check for debris, changed fuel filter. We suspect it may have something to do with the vacuum system or the air/fuel mixture, but we have not gotten that far yet. Any other ideas? Please hurry, going through rover withdrawls.
