Cold Start
 

Well before and after my SR swap which is just completed (runs perfect by the way) my car on a cold start will shut off. After a few starts and shut off it starts idles rough for 30 seconds and idles perfect for the rest of the day unless I let it sit again until its really cold and start it again. (then it will happen all over again.

I think it may be a sensor or something.

A friend said could be fuel pump but when I turn the ignition on I hear the walbro humming so it cant be that.

Any input is highly appreciated!!!
