low power

  1. B

    2003 5.4 2 valve rough idle, hesitation when stepping into it and low power no codew

    I have an 03 expy with the 5.4 that has a rough idle, low power (0-30 in 20 seconds) and no codes I replaced the oxygen sensors, MAF sensor and the throttle position sensor. Could this be timing or is it IAC? Is it something else?
