RE: [doc] re idle problems

["Richard Hutchinson" <dickyh11@xxxxxxxxxxx>]

Steve,

Have you tried what Nick suggested again over a week ago??

"As said in previous post, you can completely remove the idle speed
motor (large black can size of baked bean tin on left hand side of
engine when viewed from the rear. Block the 2 rubber pipes with a large
bolt in each (v important).
   
  Fully seat the 3 brass screws (just above the W shaped part of the
inlet manifold when stood from the rear of the engine) by hand, DO NOT
OVERTIGHTEN THEM.
  Then, undo the 2 nearest to you by 2.5 turns and then the one furthest
away by 7 full turns. This should get the car to idle at a fixed rate."
....

This simple test would have bypassed the idle speed system completely
and eliminated a whole host of unnecessary and costly bits-swapping.
