Obd Port Wont Connect

I recently replaced the motor in this 06 cobalt so I dunnno if that has something to do with it or not but I have a check engine light on n wanna figure out why.... but I get an error after the scanner tries connecting to the car. ive tried two different scanners so I know they arnt the issue.... the car has a slight sputter a few times when coming to a stop n the check engine light seems to go off when its above 4 degree outside... any ideas guys?

Do you have power at the DLC OBDII port?
Sputtering when coming to a stopis usually caused by dirty throttle body.

I was thinking the same thing. Check for voltage at pin no.16, that's your power.

Fuse for Power is usually the same as lighter (LTR).
