OK, drove to work again today, trip there, fine no CEL, decided to take a different route home and avoid the bumpy road, roughly the same amount of time passes on the new route that the old route would take and 'ding' CEl pops up.
so it's not the bumps, only other real difference between the morning and the afternoon is the car has been sitting in the sun all day.......
Had to run to the office today, drove in no CEL, put the car suspension in Sport mode, drove the rough road on the way home, no CEL. (was only there briefly)
looks like it has something to do with sitting in the sun, might still be gas cap related even though it is a new one.
Before I replaced the cap I was getting the CEL almost every time I started the car.
decided to follow dudecs's advice and put some Silicone grease on the cap o-ring, hopefully that helps
well the saga continues, got a CEL first thing this morning, first time that has happened since I got the new gas cap.
kind of puts a damper on the "soaking in the sun" theory
guess I'm just gogin to have to sit my butt down and start doing some serious debugging

Well, it's a little along the lines of me turning Ig-ON when the front bumper is off, but just thought of this:
What if you clear the codes, leave the cap off, as in forgot to replace it, and then turn her on. Is it the exact same error?
well my car decided to mix it up today, got the CEL first thing in the morning, cleared it when I got to work, parked it a spot that would be shady in the afternoon.
No CEL on the way home, even made a couple of stops.
LOL - will probably pickup a cheap smoker tool and hit the evap lines to look for cracks
well after a minimum amount of swearing and only a couple of burns(engines get hot ) I was able to reconnect the vacuum hose ont he back of the intake manifold, no CEL when I drove it.
a couple more drives and I'll be convinced that was it.
That’s the last connection I make before seating the manifold. I usually have to put it twice as I find it breaks loose the first time. Then I try my best to limit the amount I move the manifold after the second attempt. Instructions say to use a mirror To see when connecting it but I just do it blind with two hands. Then I just hope it stays and don’t really check. In retrospect: you may have connected it but maybe it popped out like my experiences.
Eager to see if that stops this! (Thanks for updating, and hope your burn recovers quickly)!
I used my bore scope to verify that it stayed in place, I'm sure what you described it what happened the first time, put in on and it pooped off when we were getting the manifold in place.
this go around I only lifted the manifold enough to be able yo get one hand behind it and plug it in, other hand was supporting the manifold.

I purchased a bore scope and found the rear vacuum line on my intake manifold had popped out of the rubber housing. The car ran rough and gave a P0455 code. I decided to finally tackle this job...again. Here are a couple of lessons learned:
The rear vacuum line in a 2010 4S likes to pop out of the rubber elbow. I tried multiple times, but could not get it to stay in the elbow. I decided to use a small ziptie to secure it the the elbow, then insert the other end of the elbow into the nipple. This worked! Here is a photo of the vacuum line I am referring to with the ziptie:
Also, the intake manifold bolts are retained by a metal clip into the manifold. When maneuvering the manifold into its proper place, gravity allowed the bolts to drop downward making it difficult to precisely position it in place without dislodging the vacuum line. I used 3M painters tape around the threads to keep them from falling due to gravity and once it was in place, I removed the tape. The attached photo shows it upside down after I placed the tape on each bolt. It worked very well and the job was successful!
