Malfunction Indicator Light eliminator. it goes between the o2 sensor and its plug in to read it correct if your cats are out. so it doesnt throw a SES light

Yes jaydee is correct I also thought it was an 04 but after checking the Vin number
Turns out it's an 03 I have been told many different things lol nice truck but yes it has the older body style which is why I assumed it was an 03

03 heritage edition is the 100th annivarsy of Ford it was a special editon available in a limited number form ford. On the MIL's the new pcm strategy codes do not like them and it will see right thru the o2. Just get a tuner to turn the rear o2's off.

They make a tuner for our gen truck that will turn rear o2 off? I didn't think that option was available for this gen

I have some mil eliminatirs out in the garage, I was going to use them on the Harley and still might if I start having problems with getting inspected, I had my tuner turn off my rear O2's so I don't throw a check engin light, but it still reads not ready when you get it inspected... oh well..
Are you using these eliminators when you plug in the new sensors? Because I was thinking maybe one of them are bad? Also, have you tried the spark plug non foulers? Just throwing that out there. I've never done it myself but those plus the eliminators may work, or some concoction of the sort.
