thanks guys will check the microswitch...
The hose from the ICV that excepts the cold start injector is new and i do agree total pain to replace, i ended up removing the air flow meter to get to it!
replaced the boot under there while i was at it.
unplugging a vacume line doesnt really do anything with the idle, maybe a little bit rougher but hardly any difference to idle.

unplugging the TPS increases the idle to around 900 and smooths it all out. not sure if thats relevent. checking with a multimeter seems to give me the correct results though.
