need some help with an idle issue, my tuner walked me through it when i borrowed my shops scan tool but all night it still wont idle smooth and it keeps having about 0-12 counts of the iac and surges. at .45v on the tps it wont even start up, it just shuts rite off...

its a 6.0 iron block with ls1 intake, emissions deleted, new iac as of this morning

does anybody know where my set screw for the throttle valve should be? my tuner want 30s for the counts but it wont go around that...so can somebody walk me through the process more in depth

thanks
mike
