Got a 2000 Focus, 2.0 zetec engine stumbles/hesitates under acceleration/load. Idles ok and I can rev up the motor just fine when not in gear. Replaced the dpfe sensor, spark plugs & plug wires. No improvement. What is the culprit? I have read a lot of forums where people had the same symptoms as mine and it was the dpfe sensor for the EGR. I have also checked for vacuum leaks using propane gas around the intake and vacuum hoses with no change in the idle. Please help!
