I've been having a heck of a time diagnosing some weird idle characteristics on this kit. As Zach suggested, I cleaned my MAF sensor which would help for a bit, so I ended up deep cleaning the Edelbrock filter and entire airbox assembly. Got a new MAF o-ring and screws while I was at it.

I've now got a really weird issue where the car runs and drives great in most conditions, except at hot idle. When the radiator fans kick on, the idle dips to 500rpm and the car almost stalls, then idle jumps to 1500, and back and forth until the fans turn back off.

No CELs, no other issues that I'm aware of. Anyone have any ideas? Throttle body is new (under 5k miles). The logs don't show anything that looks like vacuum leaking either, trims are good.
