I have used a new sensor on the existing frame before myself. The casting skewered by a steel pin is a great candidate for corrosion. Is there something bent in the shutter wheels on the inside of the balancer?

I hope you will do the tests one more time when you get the new CPS installed and the engine running to confirm the instructions for testing the CPS are valid.

I also had been dealing with a "chugging" with the 'vert. So yesterday after taking the car for a drive I decided to swap Mass Air Flow sensors with the Red and swapped in a different ICM/Coil Pack. Took it for another drive and that wasn't it. So rather then do anything more with a hot car I waited until this morning to swap out the Oxygen sensor. I keep a diary on what I do to my cars [I just write dates/miles/service done in the back of the owners manual] and saw that the plugs/wires/coil swap were done 7 years and 15000 miles ago, but nothing with the Oxygen Sensor. So that was next. Took it for another drive and that seemed to be the fix. The car runs much better, has the acceleration it used to have, and no vibration. I also had thought maybe the catalytic converter might be going bad because of the vibration and poor acceleration, but thought "Do the easy stuff first" and that was the Oxygen sensor. And that appears to be correct!
