i have a 91 coupe and since the cold weather (anything below 45*)hit my car does not like to idle. i mean it will start just fine idle around 1000 til it gets warm then the car just wants to die.like if im driving and push the clutch in and let my foot off the gas the rpms drop straight to about 250 even die if i dont feather the gass.sorry for being so long but this is a pita any suggestions?
