lets see if this helps guys a quick rewrite
ok for some reason the blacktop mk1 vtr seems to be hard to find any info on so 1st up thanks to 666 for this shame the pics went down but i figured it from this
step 1, remove your airbox - reason the pipe coming up behind it and into the top section on the right is the return pipe from the ICV
step 2, locate the icv and connecting wire needs removing do this by finding your map sensor (top left attached to the firewall behind the engine) follow the wire down just behind the first injector and youll see an odd cylinder shape with a yellow connection on it thats your ICV
step 3, remove the ICV pipe from the throttle body housing, follow the small pipes coming from the map back to the housing, next to them is a fatter pipe this needs to be uinclipped and when you remove the icv youll need to persuade this pipe to move down through the injectors
steps 4, get your hand behind the engine and push the icv accross so it slides of the rubber band its held on by, easiest way i found was to pull the pipe from the airbox end and push the sensor and in 5 mins youll have it off to clean or replace
thats the offending piece, carb cleaner and earbuds works well if your getting idle issues and random revving up, sucking air like its choking ect this be a good place to begin
