This mod will clear some or all of the No Cat Codes that the engine throws for not having a Cat.
-P0420: catalytic efficiency
-I am not responsible for any mishaps due to you doing this mod...If you are not mechanicly inclined. Please have someone else do it for you
-Please check with your local, state, and federal laws before attempting to do this mod.
-For off-road use only
Parts Needed:
-18mm Spark Plug Non-Fouler (come in 2 per pack) and are available at any autozone...be sure its the same part # as pictured
-7/16th drill bit ($5)
-7/8th Wrench
-Power drill
How To:
-Disconnect Negative Battery Terminal
-Find 2nd o2 Sensor Harness and disconnect it.
-Take 7/8th wrench and remove sensor (lefty loosy, righty tighty)
-Take non fouler out of package and secure with a vice grip (Preferably a big vice grip)
-Insert Drill Bit in Drill (DO NOT HAVE THE DRILL PLUGED IN WHEN DOING THIS)
-Support the Vice Grip with your feet or any other heavy object, soo when the drill is going, it doesnt shoot out flying.
-Do not penetrate the tip of the Fouler...you will just be drilling to open up the inside of it.
-After you have drilled some of the inside off...Clean the metal shavings off with the bottle or throttle cleaner, or brake cleaner...try to insert the O2 Sensor in and tighten. (Try drilling little by little until the O2 Sensor screws in) I left the vice grip on the Fouler and just tightened the O2 Sensor with the 7/8s Wrench...much easier and faster.
-Fouler and O2 Sensor should look like this...(If it doesnt, please stop and get someone with more "mechanical skills")
-Insert Fouler into Downpipe
-Tighten up the Fouler (not the O2) into the Downpipe
-Plug in O2 Sensor harness back (Make sure you hear a "clicking" sound)
And you done...
