Hey Zeek
We had a huge problem with out AAC till we pulled it off and cleaned it
There was a thread on here that was step by step and great !
it was full of carbon and the screw was gunked up and wouldnt turn even
came up beautiful with some carby cleaner
and the idle was so much better after the clean
We are at a similar stage as you trying to put an R32 coupe back together
!8 months later and
nearlt there
