Nissan Repair: stalling, egr valve, water temp

Question
AFTER THE CAR WARMS UP, AND WHEN I COME TO STOP, THE CAR TENDS TO STALL, THIS DOESN'T HAPPEN ALL THE TIME I COME TO A STOP. THERE IS ALSO A BUCKING SENSATION SOMETIMES WHEN I AM ON THE HIGHWAY AT SPEEDS FROM 50 TO 65 MPH BUT THIS HAPPENS ONCE IN AWHILE. SOMEONE TOLD ME IT MIGHT BE THE WATER TEMP SENSOR.

Answer
George,

When you come to a stop and it stalls.  Check your EGR valve it could be bad.  This could also cause the bucking.  

Other wise George when your on the freeway stay off the BULL and it won't BUCK!!

LOL... Just a little sense of humor..to bunt intended.

Or
it could be your speed control sensor.
