My 05 V50 T5 auto (74K miles) is acting a bit strange of late. On short around town trips and out on the highway it runs real well, the turbo spools, it downshifts and launches, it runs up to (speeding) speed real nicely, all normal.<br>After a two or so hour trip it seems to lose power....? It seems like I need to have the pedal all the way to the floor, it bogs down, it crawls up hills, it does not excite or impress.<p>I don't understand. Fuel filter? I have never changed it and bought it used. <p>Other ideas please"? My old GLT has more punch that the V50 of late.
