yea turn off the car, disconnect iac valve, short the diagnostic pins, start car, adjust the idle so it reaches just over first line, by the way the first line is 500rpm so i its more like 600 :D

i dont have 500rpm line increments they go up by 1000.... the line on the bottom is '0' and the next one is '1' and it sits just below half way

as for instructions.. care to elaborate? :S

yea mine started doing that, then the throttle position sensor and idle air control valve needed replacing, also clean your throttle body off the car, this is in the HowTo section ;) cheers

TB has been cleaned not long ago.. alot of crap in there.

wouldnt my car be throwing out error codes if i had to change them?
how much do the iac and throttle position sensor cost and are they easy to replace.. simple switch over?

no not for the iac valve, but new they are like 70 bux from holden, when my tps died it put the car in limp mode, so you will know if that does play up ;)

try taking the iac valve out, and wind it back to 28mm

ill try finding camera and make a howto
