I've got history with it and I know the idle control valve was changed last year but I'm still getting a 223 fault code, I've had a look and the hose that connects from the air filter to (what I'm guessing) is the idle valve has been detached at the block end and has also had holes drilled in it... If I reattach the hose the revs increase to near 3500 then drop back down and roll back up again.
Any of you kind folks offer any advice for a noob?

Hi if you need help with this please let me know.
The B18U used to be funny for this.
Sometimes the switch on the end of the step motor would fail.
there are also to pipes on the back of the inlet manifold that blocked up.
the one going to the MAP sensor would block and cause idle/running problems.
Cheers
