Possible fueling issues?

I was going to ask you the very same question after asking you about symptoms. :P Do you hear any high pitched whistling? I've been hearing the faint whistle for the past year, and it seems like it's on the passenger side. Evidently, it is the same one that has a minor oil leak, but not enough to drip. There's no blue smoke. The PCV hose and vacuum line to the throttle has oil residue as well. The driver side is clean. I can only imagine what it'll be like after removing the throttle bodies.

I'll have the exhaust manifolds checked the next time the car gets on a lift.

I remembered this being discussed at one time, and I thought that's what people concluded - that the cars come stock with widebands. I was just curious to see the wide band sensor parameters in Cipher. If that's the case, then I'll consider getting a sensor makeover at some point to go with the digital multi gauges from Zada Tech. Phew... gonna be pricey.
