Lately my car has been having a little trouble on the startup. If I havnt driven it in a couple hours and it gets cold, when you start it up it stumbles and misses a cylinder for about 3 minutes, than it smooths out. Seems it only misses when it's a little cold. What would cause this problem? Besides the startup, the car appears to drive just fine.
 
Could be chip design,maf,coolant temp sensor.Iac may need cleaned,Tps or butterfly adjustment.
 
Ok...I did a little test today on it...seems it's the number 1 cylinder is the cylinder not firing right away. After about 2 mins it starts.
