I HAVE 2 DIFF INTAKE VALVES 1 IS G5S & THE OTHER IS G5M. DOES ANYONE KNOW WHAT THE DIFF IS BETWEEN THE 2?

I have searched and searched but found nothing with similar symptoms. When the engine is cold and I start it, the idle is low and tries to stall on me unless I keep feathering or steadily give it gas. Then if I try to drive it, its very lean, no power, and tries to stall under load.   Once it is warmed up everything is fine, tons of power and idles great.   Idk if its the CTS or what but I can't find anything else.

Looking mainly for the ignition module / pigtail as well as the gr sensor pigtail.   Cant find anything on ebay
