ok guys in the past week i blew my turbo motor and yanked everything out and went back to stock....my only problem is now the car runs fine on a ls & gsr bin...slighty better on the gsr map...

my problem being is that id idles perfectly and then all of sudden dies...starts to slighty misfire and drops down to like a 4-500rpm idle w/ severe hiccups...ive tried everything from adjusting the iacv in crome and @ the tb

it doesnt do it all the time either...its like workin workin workin....idles nice at 850ish...then drops and starts goin to ****

to add im running open loop since i dont have a o2 sensor yet....any insight guys?
