tunning M30 to best idle

[genphreak]

well ... I have marked the spring in the AFM before changing the position ... I'm planning to change it anyway since the resistive line has got a groove already. I have checked for leaks and all small pipes are new. ignition system could be old now ... dist. specially ... ICV ... is that the Idle control valve? I washed it with W40 and made sure its not stuck.the whole question is ... whould I still have the idle misbehaviour even after replacing the AFM ?if you still expect leaks .. where should it commonly be else than plastic hoses.Thanks Jeff ...

Dude, run the AFM back to stock position. I ran mine up 3 notches previously (we talked about it back then) but it gave a result only whilst i had a vacuum leak (ended up being from the pan gasket). Since I tightening the loose pan bolts it ran better, but still had bad economy soi my attention was turned back to0 the AFM (everything else is new). Ran AFM back to stock position (still unsure if the spring has changed due to age or not) and economy improved - perfromance unchanged. I have to get a new AFM too, but it will go when I get round to installing the SplitSecond PSC001 or a Megasquirt so till then it it is making do... Nick
