gave all that a clean today mate took of the throttle body and everything, used carb cleaner (great stuff) till all was silver not brown then wipped dry with cloth and ear buds, i noticed when i pushed the throttle back a little it idled better so i lossened the screw to make it sit further back (if that makes sense), less air (as above), there are no more holes or cleaning i can do around that part however i did notice a small rip in the paper thing that holds the throttle body to the cylinder head (prob wrong name but hopefully you know where i mean) where the air goes in past the throttle body to the chamber but it hasnt ripped all the way through, ive looked over the forums hense the split boot (think u mentioned that), cleaned all connectors with WD40 and tooth brush, i can honestly say its clean, ive also bought another 2 rubber boots an ICV with bellows, as im keen to sort this out. 1 thing though when i was cleaning i looked into the hole where you would change the mixture and noticed a clean scrape as if some1 has tried to change it with a tool, having read the forums i wouldnt go near this, also my spark plugs were rusty / orangey colour at the bottom and i read somewhere that means rich running, really wanna do all myself but if some1 has played with this could it make the car idle quicker also that would be a garage fit right???????????
