CAR CONTINUES TO STOP WHILE DRIVING. NO WARNING ON THE PANEL I SIMPLY TURN OFF THE CAR, RESTART AND CONTINUE. THIS SEEMS TO BE HAPPENING MORE OFTEN.
Give the mass air flow meter, full air intake and the throttle body a good clean. particularly the butterfly flap closing area. You’ll probably find gunk built up around the butterfly that is now restricting air flow at the closed throttle position - this will kill the engine, even at highway speeds.
Special cleaners are available for this job.
