    Drive it as least 15 minutes to get everything up to operating temp,unless the problem still comes back in 2 or 3 minutes, if so... O2 sensor may not be the cause.

    Dont delete em,pcm will constanly be in open loop and you will use more fuel than you need to among other things.Figure out which one(s) is bad and replace it.Also,make sure its not a wireing harness problem with the O2 sensors.

    Just went outside going to remove the o2s and the driverside was loose and the passenger side wasnt to tight either. Maybe ill tightem up and try it again.

    I have a Snap On scanner with several cartridges that I have not used in forever. Do you know or remember if it wil show the O2 values for a Ford? I'm certain it will on a GM but don't recall for a Ford.
