Nice little trick. Need to get this done to 08'' F150. After I put my long tube headers on my check engine light hasnt gone off since. I'll have to give this a try!!

I did this and still got the codes so I'm thinking my sensors are bad?

so is this going to take the engine light off on my truck since its an o2 heater ??

stephen_miller09

and will it work for all 4 of them not just the back ones ?

will this work on my 2010 5.4 3v it keeps clogging cats so I wanna gut them but not throw any codes

I have done this on my Camaro with hi flo cats and it works, but you might want to figure out why you keep clogging cats. Something isn't right. Here is a bit more expensive alternative, but interesting non the less.

I have an 05 F150 5.4. The cats stopped up on me and so I cut them off and cleaned out the honeycombs. I welded them back on and now the O2 sensors on 1 and 2 are showing bad and it dies on idle.. would this trick work in all 4 O2 sensors???

Question,. I had a CatylCatylatic Convert go bad. Couldn't figure out which one so I cut all four of them off and beat out the Honey combs then welded them back on. I have a 2004 f150 5.4. Now my o2 sensors 1 and 2 are showing bad. Wondering if anyone can tell me if the spark plug Fowler trick will work on my 2004 model...

tsigwing

it should. If not there is one that has a small cat with it. They cost about $50

Do not do this to all 4 sensors. The sensor on each side that is closest to the exhaust manifold (the upstream sensors) are what the ECU reads in order to keep the engine running properly. You need to leave these alone.

The sensor on each side that is after the catalytic converter (the downtstream sensors) only tell the ECU if the cat is working properly. Those are the ones that are turning on the CEL. You can do this mod to them.

Personally, I rather use a specifically made MIL eliminator. I've had a pair on my mustang since around 2004 and they work perfectly. They should also work on an F150.
