I have been working on my truck trying tomake run like it didbefore.Engine check lite was on andit was running badseems like it runs super rich withblack smoke and terrible gas milage as if it wasant bad before. I hooked up my buddies odb2 and got 02 code so i replaced it. the lite turned off for a bit and came back on so I hooked it up again and got code for the other o2 when i pulled it out it was bent out of shape so I replaced it. The truck ran good for aa bit and then started agian. I checked my cat and it is empty. Ithen unplugged both o2 sensoe and it is running better. I don't know if i should get an o2 simulator, replace the cat or run it as is. Can I get some opinions on what to do ( besside taking it to a shop so they can rape Me ).

Thanks

 

i would go with o2 sim, leaving it the way it is will just eat gas, keep popping 02s will just burn them up cause no cat, and cat is restrictive on the exhaust giving u a lil less power

 

I will install an o2 sim.can anyone tell me where to buy one ? Thank's
