What would cause these pids to stutter?

This is a pretty stock 02 express van tune in my Jeep. The log shows a number of pids in what looks like a short circuit. Ideas?

Was that captured using V2 BBL...?

V2 passthrough to laptop with all the latest updates for BB logging. It was a new flash but I had a successful capture with the previous tune. I hadn't seen this before. I'm thinking ground perhaps?

Yes, could be grounds.

I was thinking that it might be a sensor ground problem (TPS, ECT), but then I saw IBPW1, SHRTFT1, AFR... these are not sensors...

I see you're logging 29 channels... see this: showthread.php?p=71106#post71106
