I highly doubt it's the CPS... Not once have I gotten the CPS error code (P0335).

I changed it as a measure of good faith, but there was absolutely zero change in the behavior of the vehicle after the new CPS was installed.

Regarding grit, I can confirm the CPS was squeaky-clean upon install.

Les may be onto something regarding the plugs... After all, the issue started immediately after they were installed. Steve installed them, but I haven't complained about the help because the price was right and he was gracious enough to assist with the install while I was at work (we were in crunch-time mode for the event).

If the plugs were loose, wouldn't the issue occur regardless of temp? That's what has me baffled.

Thanks again for everyone's input... greatly appreciated.
