Two things first, as Fezagero says, replace the fuel filter if you haven't already. It's a must do before you can check anything else. Second, as Fez. just found out, a blocked or choked catalytic converter will cause these sorts of problems. Cats are probably the most overlooked cause of ëngine" problems on modern cars.
