IAT causing massive throttle lag?

There's no way you are seeing IAT's that high above ambient with the factory airboxes and especially at only 85 F -- I live in FL and datalog, so trust

There's no way you are seeing IAT's that high above ambient with the factory airboxes and especially at only 85 F -- I live in FL and datalog, so trust me on this one.

It's almost definitely a weird fuel trim or just the typically laggy OEM throttle response. Even if you were logging vastly higher IAT's than ambient, I'd predict a faulty sensor before an actual physical condition.

If you lived somewhere getting closer to 100 F and sat in stop and go traffic all day, I doubt you'd see IAT's go anywhere near 200 F.

Lots of things can cause laggy response (any number of sensor failures, vac leak, etc), but I'd be really stunned if you had actual IAT's confirmed via data log and a second underhood thermistor that showed this to be the problem.
