Car feels normal while driving but when coming to a turn and or a stop that requires deceleration the engine stalls. Sometimes during an out and about trip it helps in avoiding some of the stalls by putting the transmission into neutral when approaching the turn and or stop and then back to drive to continue. I have used carb cleaner, injector cleaners and manually cleaned the air intake and butterfly. I have replaced the spark plugs. I have used a plug in auto tester under dash and have come up with no fault codes in several attempts.
