Hey guys just checking in. I unplugged the upstream O2 and it is still spitting and popping. The idle will run at 1000rpm, after being brought to a stop or when started, for about a minute then tone down to an almost seemingly stuttering 500rpm. I havent tore into the intake to change the IAC yet, but thats next on the list I suppose?

So, you unplugged the upstream (Bank 1) O2 sensor and nothing changed? That would tell me that that sensor is bad, probably. Not 100%, but if you remove a suspected faulty sensor and nothing changes, then it's probably faulty.

^that's safe to say^

However it also indicates a bad 02 sensor since the idle dropped down to around 500.

It honestly sounds like a combination between the 02 and the IAC.

PROBLEM SOLVED. Changed the upstream O2, and for the sake of this form, Ran it with just a new O2 and solved the back firing issue. I also have changed the Cat Converter for other issues and Now the exhaust sounds much better.

Glad you got it fixed. What brand did you go with?
