Ha ha! Was waiting for that! Sorry, getting on here was hard enough for me! Tickover is rising and falling, so looked on here last night, and cleaned throttle body today. No better, so started looking for leaks. The bit the tb bolts to, comes over the top of the engine, and has 4 holes at front of it, about 30mm each, where the next "bit" joins to it. One of the rubber seals there is broken, can hear it sucking when I put my finger over it.
Waiting for manual to arrive, sorry for no having right names for bits!
