carb cleaner! & and lots of it!!!

Get a flat head screw driver, rotate and open the ICV.

Fill with carb cleaner, and leave for 5 mins. Shake it about and empty, then spray more carb cleaner! use a cloth to clean the bigger pipes.

Stick the screwdriver in the pipe on the top right, push in and down. It will open the ICV. spay the carb cleaner in until its full.

Leave it standing up for a while  :y

NO - DO NOT DO THAT.....you risk damaging the valve face and causing it to stick.....to open the valve, insert a small screwdriver in the front opening and slide the valve body round by pushing against the letters cast into the body...

Its worth realy soaking it well......fill it up as much as you can with carb clenaer and then cover the two openings with your finger and shake it.......lube with a light oil afterwards.

Sometimes a small paintbrush is useful for getting some of the crudd off.

Thanks guys for advise..will get some carb cleaner in morning from Halfords and do as advised..do i just fill it from top pipe entry as per photo and just stand on end for several minutes..then shake and empty?where does the oil then go and how much?  assume it gets blocked up with burnt oil etc so could have been my erratic tickover??

When i cleaned project A's V6 ICV that valve face in the right tube was covered it kak, had to scrap it off. I found it easier to rotate the ICV though that pipe than the top pipe.

But advice taken, next time i will use the top pipe  :y

Sorry Tunnie...the conversation flow seemed to direct that at you rather than IACV  ;)
