If your car was mine, I would do two things. 1 buy a scangauge or similar scanner and get the temp reading directly from the ecu. 2 buy an inexpensive IR thermometer and take the engine temp at the upper rad hose when you suspect it is overheating. SOURCE: engine cutting out when idling or slowing down Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues When the car (an automatic) is engaged in gear (reverse or drive) AT IDLE (foot on brake) the car shakes A LOT. The reason it is noticed in automatics, is that the auto engages the car and we are only holding the brake which means there is torque transmitted to the CV axle and ultimately into the CV joint.
