Whilst in the run up bay, just about to do my mag checks the engine developed a severe miss, Cylinder 3's EGT and CHT both dropped away to zero.
At approximately 1,000 rpm and with a bit of leaning i could get the Number 3 CHT up to about 150 degrees however if i tried to advance the throttle further the CHT would fall away to zero.
I shut down and restarted, immediately after restarting I noticed No. 3's EGT went straight up to about 1200 degrees way ahead of all the EGT's, meanwhile No. 3's CHT remained low.
I?m no expert, but here is my list of possibilities in order of preference.
1. Blocked injector
2. Induction leak
3. Stuck valve.
