certainly be interesting to see if this cures the dodgy 90 deg c issue.
i can see injector issue giving a lumpy idle yes ,but whats going on at 90 i cant get my head around.
i lookeed through the maps(all i could find) after reading in your other threads but all i could find that would be affected by temp was fuelling / engine temp limiter and this would only limit max fueling (i think it was around 70mm3 at 90 deg idle speed)not the sort of iq required on idle which is more like 5-10mm3
hope it sorts it, if it doesnt no doubt when it hits 90 the amount of lumpyness will be reduced with injector sorted.

i find letting it tick over on its own shows variation in injectors more, as it is being revved the speed is increased and the ability to sense variations in rotational crank speed much less i would think.
mine would always go from just over or just under 1 at idle to very close to .2 to vero when revved.
bear in mind thats all the injector correction is doing trying to give an even crank speed on all strokes
if it doesnt get any better with injector sorted you may be looking at valves or piston rings or head gasket issue on that cylinder maybe worse case, not read any similar issues so i hope its not.

check that they swapped the injectorcodes to match by checking in fes.
look for the 8 unit code i think on the top of the solenoid and compare with data from fes, if they havnt switched the codes round i think you can do it(unless its only paid version)
but codes and injectors have to match or running will be as bad as before
