I'm consolidating my answers to all responses here: I am not 100% blaming the ECU- yet. I haven't even started troubleshooting. I was making a comment that my car seems to do what the last 3 folks' cars did and I'm wondering if I have the same problem. I will say that my idle thermistor is only 17 months old. (Of course we all know what happens when I say that right) I haven't read resistance across pins 1 and 9. Thanks for that info. So far, the car has only done that high rev one time in several weeks. I also haven't has a surge while driving in weeks. I appreciate the info regarding the wiring diagrams on DMCUK and thanks to Elvis for dissection one for improvement.
