Saw on another post to unhook the 02 sensor and see how it runs.

1. What will this do.

2. What are my 02a even doing that is important since I have no Cat and am running PS Longtubes??

3. I have one new and one old 02 the new one is on the psg side Header the old one is on the other header.

Is unplugging both of these going to do anything?? It throws 02 codes now as it is.

 

Also can bad o rings on Injectors cause a random misfire, or cause the engine to load up???

 

The engine uses the O2 sensors to set the air fuel ratio. That's pretty important...

Bad o-rings on the injectors create a small vacuum leak and unsteady idle....thgey don't generally cause misfire problems.

It's really impossible to diagnose a problem when ther are issues. Fix the O2 sensor issues first then address the others...
