bad knock sensor?
i bought a 2004 f150 fx4 5.4 about a week now and when i brought it home it started ideling ruff and i thought it was sort of sluggish for being a 5.4 and all. i replaced the air filter as well as cleaned the throttle body and checked the plugs and it continued to idel ruff, so i took it into the garage and put the code reader on it and they said i have a faulty bank 1 knock sensor, would this make my ford run like crap? please help
