ok guys. its started to get cold again.. and the past few days its probably been around 60* (thats cold here in texas..) and when i start my car in the morning it starts. revs to about 1200 and then like imediatly drops down and stalls or almost stalls.. unless i hold the gas and let it rev for about a min.. then it will hold an idle.... the CTS is pretty new so i know its not that.. but i will double check it on the scan tool tomorrow, along with IAC value.. but one thing i have noticed is when i start to drive off.. i have to rev the engine pretty high and slip the clutch alot. but the engine always wants to die as soon as tap the gas. so i have to press it quite a bit in order for it to actualy rev without acting like its going to stall.. what could the problem be??
oh and also i just installed a t-56 and removed the stock shifter.. so i think the ecm always thinks im in drive or whatever.. so wouldn't that keep the engine from idling as high as it normaly did with the auto in there...

 

yup.. ran like crap again this morning..... and its gonna do it again tomorrow...
