Can someone tell me where the Idle adjust screw is on a KA24E.  I read my chilton's manual and it shows me where it is on every other engine except for mine.  My car has been idling at about 1500 rpm for a while and its been annoying me.  When I first bought the car back in DEC it was idling at around 700 rpm.

There should be a big open port (casting) on the front of the throttle body.  Inside is a big screw.  Kinda hidden under the filter box I think.  Or wait, is the filter on top with yours?  I'm going from the truck ka.  

The last time I attempted to adjust it, I read the manual, and it went off on doing without the engine on or computer will go messy.

I'd just turn it with the engine running and see what it does.

The filter on mine isn't sitting on top like the ones in the truck.  I'm still going to take a looke though.

 Does anybody know how much it'll cost to run all new wires in the engine bay.  Mine are pretty much shot.  There's a sensor on the front of the engine right by the fuel rail, I think its a water temp sensor, but anyway when I mess with it at all my car starts to run rough so I'm thinking about just changing all of them.
