If I unplug my upstream O2 sensor, will that force a "rich" condition? In other words, will it force a rich commanded AFR? It should change if this is not my current issue for my rich commanded AFR, right????
Really? Disabling the #2 O2 sensor MIL is pretty common, but I have not heard of disabling it for the #1.So John...I think I FINALLY have the answer. Apparently the tuner that did my tune shut off the O2 sensor CEL. I just went down to put gas in my car (about 3 miles each way) as I was going to drive it tomorrow to work (about 14 miles each way). And my Torque app FINALLY showed this message on one of the gauges:
Fuel Status: Closed Loop 1 O2 sensor (fault)
So I'm going to guess that this means sensor 1, the upstream O2 sensor (wideband)?
Too be honest, the vibration is gone...so I'm "hoping" this is the issue!!!! :yay:
Of course I've been known to be wrong before!! LOL....
NPThanks for posting this thread Ghost as its a real learning curve for me.
Nothing about the AFR is going to make a "rushing air sound". You must have a leak somewhere.............theres a lot more rushing air sound when I get my 23psi of boost. All of this tells me something has changed. And the only thing logical right now is the commanded AFR........
