Recap, replaced head gasket in another post....so today, after driving the car for a few days it just cut off this evening....will start back up but wants to cut off at idle..almost like something is shorting out, engine light will flicker when it wants to cut off....won't do it everytime...it wants to die when I put the car in reverse? Looked at it in the driveway (dark outside and late) will pull a code tomorrow...any ideas to look for?

 

pulled a code today...speed sensor, changed out and all is well
