My Xb9sx 2007 is running rubbish again it's taken the afv and ego to 89.6 and was flat 2500-4000rpm before that didn't feel right about 2500 like it had slight miss fire ok over the rest of the rev range. Got it home 20 mile ride when I got home the fan wasn't even on went to get my laptop plugged it in and it said the engine temp was 119c though it would have been higher.
Any ideas no fault codes, temp sensor, coil breaking down , ht lead?
Mods k&n filter, breather rerouted, Albert exhaust, race map

Check the fan works on interactive test

Let the engine run and see what the max engine temp is
