Sludge build up in the throttle body can cause a poor engine idle, stalling, and/or hesitation. The correction is to install a new idle air control valve spacer kit to prevent the sludge build up, set the base idle, and clean the throttle body.

my car stalls while im driving or at a stop light. it does it more in the summer time than in the winter but i had my cam sensor replaced a month after i bought the car so i dont think it's my sensor.
