2010 LS3 E38 Camaro (build details in signature below). I have a 112mm Nick Williams throttle body on it. I noticed that during a full cold start (been sitting overnight) it starts and seems to idle ok. But the second I try and take off?the car has been bogging down and throttle flaring and then stalling out. I then go to restart it, and it starts really hard, and then there is all sorts of clicking and clanging coming from the throttle body. Like it?s trying to find ?home? or it?s range settings.
That then translates into an almost impossible situation to actually drive off with?because the throttle blade seems to be hunting and it keeps throwing the car in and out of boost. After about 2 miles and the car warmed up a bit more?it seems to go away. Then hot starts?no problem at all.
Is there a throttle learn setting that needs to be looked at? Car was tuned by a professional and well known tuner here. But having a hard time catching him via phone. I may eventually get to him?but thought I?d try here to see if there is something obvious to look at.
