when i bought my corrado the idle adjustment speed screw was missing. i got one from the dealer and stuck it in. i need to know how far this needs to be in/out. the screw is the one in the back of the throttle body, it has a o-ring on it. let me know what you guys think...thanks...

Re: idle speed adjustment screw (just g60)
The Bentley says to make it idle at 800 +/- 50 rpm with CO content between 0.4 and 0.7%. So, turn it till it idles around 800.

Re: idle speed adjustment screw (LysholmG60)
The ECU is responsible for controlling idle to begin with. Don't know why there's one in the back of the TB. Screw it in there and make sure it's in tight so as not to come out.
You're lucky...my idle screw is broken in half. I've got to dig the rest of it out to put the new one in.

Doesn't seem to do much for me unless I really turn it in all the way, then it slows the idle, but just barley.
Like BrewDude says, the ECU is responsible for the idle on our G60's.

Re: idle speed adjustment screw (TexasCorradoG60)
so if my screw is in almost all the way in, i just changed my computer chip, and my idle is going up and down at like 600-750 and i give it just a little throttle to 800-900 it sounds great, what do you guys think?

Does it change any if you mess with the idle screw........as I said above, it does not do much for me, but then again I might have a problem that I am not aware of.........after all its a Corrado!

Lots of things could be causing your low idle. I doubt it has much to do with the idle adjustment screw, since they seem to be an all or nothing thing - ie either it is there and plugging up that hole, or it is missing and causing problems. Check over all of your vacuum hoses, little leaks through cracks or frayed hoses can screw with your idle.-Nate
