1- Got into it in 1st gear getting the r's close to 5k, and it felt like the accelerator pedal kicked back towards my foot. Shifted into 2nd & 3rd, brought the r's up again, was fine. Tried it again after a mile or so, did not do it that time. All future heavy throttle in 1st gear did not duplicate the kickback. Thought that was kind of unusual....
Are you sure this is not ASR activating?

2- I noticed that when the plenum pull was done, and the vacuum issues were addressed, when first turning the key to the on position to hear the vacuum pump, it only came on for about 2-3 seconds. Today when first started, it stayed on for 3-5 seconds. All repeat "hot" starts just turning the key to the on position did not activate the pump at all.
This type of variation is not unusual. I wouldn't worry about this.

3- Reason #2 has me concerned is that the idle is still not quite right. And at one time today, it did go as high as 1200 r's when I came to a stop. Sometimes it will idle at 650-700 r's when stopped, other times it will be at 900-1000 r's when stopped.
We'll investigate when we have our WAZOO meet.
