just a note, on my 4K when i put on VDO temp sensors, you could see the water temp changing quite a lot. (when idling)
the temp would start to rise from thermostat temp (82), and take maybe 1 minute to creep up to 90-92deg, then it would quickly rise to about 95, then go quickly down to 82 in about 5 seconds... temp sensor was directly below thermostat.
as far as i can tell, the is perfectly normal operation for a thermostat that is just outside the block, on the "outward path" of the water...
ie water slowly warms up but temp inside block is higher.. when thermostat is hot enough to open, all the warm water flushes out, and is replaced by cold radiator water.. when the cold water hits the thermostat, it closes up again.
to relive this a bit, i drilled a 3 or 4mm hole in the thermostat to allow a little more flow during normal operation, rather than completely blockink (and having weird temp changes inside block)
as for your idle prob.. intake leak? what else causes idle to go lower and start popping apart from going lean? (ahh the good old carby days  )
Cya, Stewart
