I have a P0021 code popping intermittently after a slight hesitation, with CE, VSC lights coming on. All three times my wife was driving and going less than 15mph. goes off after a while, but never does it when I drive (theres a brick in my shoe...). Other notes is it didn't happen until started getting COLD (in the 30 degree F). Research on the forum doesn't confirm a smoking gun. Any experience out there?
06 V8, 202K miles, up to date on all service.
Please and Thank you.
Edit: Is there a VVT oil filter on the V8?

Possibly. oil was changed about 2K miles ago. seems to be something that goes bad on other vehicles regularly, but not really seeming to be a trend on the T4R, V6 or V8
