Unless I am wrong, that is how you adjust the 'base idle', which shouldn't usually need adjusting, but I have used that screw to tweak down the idle a number of times without any worry. Don't think there is any other way of adjusting the idle anyway...
How is the cam going, have you got it idling yet???? Let me know how it goes because i am close to getting the crow from revheads for $245. Did you get the timing chain or the vernier cam gear as well????
To adjust the base idle, you can do it the hard way - ie ecu in diagnostic mode, follow your gregorys book for that, or you can do it the easy way.
The easy way is start the car, let it idle in neutral, and disconnect the ISC plug / socket and you'll notice the car will idle down or possibly stall, if it stalls turn the screw clockwise 1/2 turn and start it up again, basically, use the screw to get it idling at about 600 rpm, then reconnect the isc plug.
It may idle a bit fast at times, until the ecu relearns the idle settings, should only take a day or 2
yeah i think a bolt was dropped, but it wasn't me cos i didn't put the cam in. There is nothing in the sump except for a little bit of shrapnel, so proving that the pricks who put my cam in did it is going to be hard to say the least. Thanks for the info guys, atm it stalls at idle so was going to make it idle at about 600/800rpm to combat this if it can't sort itself out.

After screwing idle up you "may" have to check that the t.p.s isn't set too high I figure its similar to V8's should be under 1 volt..Or the eec thinks your at part throttle...As Above is correct...
To adjust tps the holes need elongating with 1/8 drill or file so it can be turned...
