The we mecanic m8 is bleamen it on the plug/sensor at the tb and says to swap it with the other one on other engine. Could there be anything els that is doing it.

check for an air lock in the cooling system also the iacv could need cleaning out or adjusting

the 2 valves to worry about is the one underneath the throttle body which is the fitv and the other the iacv which is on the intake plenum behind the injectors as you look at the engine

air could have become trapped especially if it ran a bit hot on the trackday
