Ok interesting, I just had the fuel filter replaced about 8K miles ago, and my K&N has only about 8K on it, and as for the O2 sensors, it may be worth a shot! I'll double check the MAF also. Thanks!
2000 Contour SE V6 ATX (White) K&N Moose fixed finally! Dunlop SP Sport A2's Sylvania Silver Stars (low and hi) Lots more coming!
