Does anyone know if this mod will work on an '07 5.4 with the oem sensors?

I've been searching through threads but can't seem to find a definite answer.
I already bought a set of tapered and gasket seat non foulers...having a coworker drill out the tapered ones to 1/2" using his drill press, but it might be a few days before he gets around to it.

I'm currently running Magnaflow 94106 cats and keep getting the occasional p0430 cel. I'm do for an emission test next month, so I'm trying to find the best way to keep the cel away until after the test.
I ran ethanol free fuel a month ago and it seemed to stay away for longer than on E10 but not sure if this was a fluke.

If anyone has any ideas, it'll be much appreciated!

 

This site is sucking more and more. Look up f15dyboys on Facebook

 

I have used this method on multiple vehicles that were having O2 sensor issues or after removing catalytic convertors. I have always had good luck with it. You may be better off replacing whichever O2 sensor is giving you issues or checking your catalytic convertor to see if it is funtioning properly. I found the easiest way to check my convertors is to use a laser temperature sensor and read the temperatures at the inlet and outlet of the convertors. Make sure you don't read it from the shields, has to be on the actual convertor body itself. If they aren't working correctly the temperature will be the same. If it is working, the outlet temperature will actually be higher. Hope this helps. Good Luck. And in my opinon the only thing that sucks on this site is the dweebs trying to run it down and send members elsewhere without earning it.

 

Well more than likely I'm getting the code because of the cats...they're pre obdII.
I'm just trying to keep the CEL off so I can get a new inspection sticker.

 

I would think it would work then. I've done it to a couple other vehicles with success. Not to this new of a truck though. Your not out much by trying.

 

Well the 1/2" hole isn't big enough for the sensors on my '07 so I'm using the heat sink, bung extender that I use to monitor AFRs on my jet ski. I only have 1 so I put it on the driver's side to see if the code stays away.
Unfortunately I got 2 codes this morning...one on each bank, so it looks like I'm going to need one for the passenger side too.

Guy from work is still gonna try to drill the defoulers a little bigger but there isn't much room left before it starts eating into the outer threads of the defouler.

 

My experience has been that the hole just needs to be large enough not tocontact the tip of the O2 sensor. Never had too many issues. You may have totry one of the O2 simulators some of the racers use. I've heard that's kind ofhit or miss though. Let us know the results.
