O2 simulators question

I have a 2004 4.7l tundra and recently put headers on it and got rid of the exhaust. I purchased some URD O2 simulators and am having a hard time getting them dialed in to get rid of the P0136 code. has anyone used these and had good luck with them? Or did I waste my time and money? Any better options would be greatly appriciated. Thank you!

 

Can you send me some pictures, i would like to see what you did to remove catalytic converters. I would like to do the same

 

Don't have pictures but I had a plugged converter on drivers side that caused a head gasket failure, so I unbolted them and knocked all the crap out of them with a piece of rebar and reinstalled them. Also put shorty headers on it at the same time.

 

Also cut the resinator out and had an exhaust guy do cat back exhaust system

 

Call URD. Gadget was always very helpful and I'm sure he still is.

 

Your truck is not to pass smog. What do you plan to do when its time to get smogged

 

not a worry in wyoming

 

A great State from what I’ve heard.

 

Keith @dirtydeeds might be able to help

 

Great state indeed!! I grew up in Wy. Tn is home now.

 

Anyone try o2 sensor bung extensions? I’ve done this on a few of my past vehicles without issue. Can’t go wrong with a mechanical mod. I’m wanting to cut the cats out on my 2nd gen once I get it into the shop also...

 

would only work on the front O2 sensors. The rear ones are a different design with bolts built in to them.
