Over revving and other issues
#57
Another suggestion. Look at the integrity of the throttle arm - linked to the throttle spool. Is there ANY slack in that? There's a small 8mm balljoint on the lower half of the arm where the link arm clicks on to. Is it still tight with no wobble? This was one of my areas of issue. This, along with another few things was meaning the car wasn't returning to the fully rested position at idle. When the throttle spool is at idle position, when it clicks the idle speed microswitch (presuming it IS doing this!?), if you push with your finger at the top of the arm towards the fuel distributor, can you get any movement in this arm at all, possibly then resulting in a drop of revs (or not) even though the idlespeed microswitch might be clicked?

How does the engine perform at idle with the CSI disconnected (disconnecting it BEFORE you start the engine!)?

Be VERY careful if you remove your fuel distributor to allow that plunger to fall out. It must be stressed that if that thing drops and hits anything hard, it's game over for it, and you'll need to buy a replacement. It's a precision piece of engineering with very very small tolerances, so if it gets damaged in the slightest, it wont work any more. Just a warning.
