Well, I couldn't take it any longer and I HAD to see my baby!
So, I pulled the cover off, unhooked the Battery Tender, hit the key and she fired right up! I received an AutoXray EZ-Scan 3000 for Christmas, so after letting it come up to about 150 degrees coolant temp, I shut it off, hooked up the scanner and started it back up. First off, the car has a very uneven idle. "Bouncy" is about the best way to describe it. Not very smooth. It's a little smoother in park vs. gear, but not much. It also has a very rich-smelling exhaust, and LOTS of steam-like vapor from the exhaust.
Here's what the scanner told me (I'm posting only the pertinent stuff):
A full trouble code scan returned "No trouble codes found".
Left Block Learn: right around 128, but would fluctuate a bit.
Right Block Learn: 160 (I know, not good)
Block Learn Cell: 16
Left Integrator: Fluctuated quite a bit, but in the neighborhood of 128
Right Integrator: 135 average. Consistantly higher than the left.
Spark Advance: 22 degrees
Loop Status: Closed (went into closed loop after a few minutes of idling)
Both 02 sensors were right in the 570-580 mV range, which I belive is about normal. However, there were times when there was quite a difference between the left and right.
I'm thinking either a bad injector in the right bank, or a flaky 02 sensor. But most likely injector(s). I do have a digital volt-ohm meter, but it's just too darned cold to stand out in the garage and take resistance readings on my injectors! I also got a fuel pressure gauge for Christmas too (boy, Santa really knows his stuff), but again, using it ould have required me to get out of the nice warm interior! As soon as the weather warms up (come on Spring!), I'll be checking these things out too.
So, would a bad injector cause a rich condition and rough idle like this?
