ok so i have a 2000 coupe with a h22 swap with a skunk2 intake manifold type-r throttle body cold air and a full exhaust running on a stock p13 when i start the car after its been sitting a while in the cold and i start it it idles at like 300 rpm's wants to bogg out and it will stall on first start up and then it feels like its misfiring untill its at full temp. anybody have any ideas?????

 

maybe thermostat...or it can be ur idle is to low...maybe you have to adjust your idle...

 

bump! thanks!

 

Coolant temp sensor will cause this issue because ecu does not know it is cold so won't apply the "choke"
