OK..some new info to throw around...
I tried something different today to see if I could induce the problem quicker at higher RPM's. So, I decided to drive to and from work without the OD on. On the way to work, there were only some hints of trouble but nothing major. On the way home, my CE light finally came on again (probably as a result of numerous "misfires" over the past few trips and this was nothing new, it always eventually goes off a day or so later).
However, I kept the OD off and from a dead stop to accelerating onto the highway to get up to 60 mph, the TAC was jumping wildly anywhere from 1500 to 3000 (though understand my car was shifting normally and not "jerking" or "bucking" around wildly in response to the same TAC variations) Then, my CE light began flashing for about 10 seconds.
My question is, when the CE light flashes, does it ALWAYS reflect an emission problem? I have already replaced my Cat Converter during this process and I have not thrown any codes for any emission related components. I'm not smelling any odors either. So now I am more puzzled than ever.
I cut the OD back on and took it easy the rest of the way home. Checked the codes by odometer again tonight (I don't have a scan tool) and still only 12, 43 and 55. Translation, "multiple cylinder misfire", same old same old.
Now what??
