your trucks a 96 and dont have an o2 after the cat?

 

Nope. It's a 2wd idk if that makes a difference though

 

it makes a big differance o2 sensors sence the amount of gasses coming out of the exhaust the cat should burn most of them off the one after measures how much is left over shich should be little to none. if the o2 behind the cat senses to much gas it will starve the engine thinking it is running to rich to little it will increase the fuel to air mix. if you dont think you can handle the job don't mess with it

 

Eh? That's the job of the initial O2 sensor(s). The after cat sensor is for monitoring catalyst efficiency.

 

that is what i said in a really simplistic way.

 

No, that's nothing at all like what you said.

 

yes it is sorry you can't read...

 

Perhaps the issue is in your inability to use proper spelling, grammar, etc. You stated "if the o2 behind the cat senses to much gas it will starve the engine thinking it is running to rich to little it will increase the fuel to air mix."

This is incorrect. The O2 sensors in front of the catalytic converter are used for measuring the proportion of oxygen in the exhaust stream and adjusting fuel trim accordingly. The one after the converter is used to verify the operational status of the converter itself, not to adjust fuel trim.

 

Prehaps i don't give a **** and now will ignore you if you can't understand me don't listen to me simple as that now isnt.

 

ok calm down was just a big miss understanding. like i said the o2 after the cat is only there to tell you the cat is good. the o2s before the cat adjust fuel trim and all that.
