Consumer Description

IDLES DRAMATICALLY WHILE THE CAR IS AT A STOP, AND THE ENGINE STALLS VERY FREQUENTLY, REGARDLESS OF TEMPERATURE OR WEATHER CONDITIONS. ON START-UP, OR WHILE STOPPED WITH THE ENGINE RUNNING, THE IDLE WILL BECOME ROUGH AND VERY BETWEEN 200-3,000 RPM. ALSO AT TIMES, WHILE STOPPED, THE IDLE WILL INCREASE FROM NORMAL, SMOOTH IDLE UP TO ABOUT 3,000 RPM FOR APPROXIMATELY ONE SECOND, THEN DROP BACK DOWN TO 750 RPM (NORMAL IDLE SPEED) WITHOUT TOUCHING THE ACCELERATOR. THE AUTOMATIC SHIFTING FROM 1ST TO 3RD GEAR COMPLETELY SKIPS AROUND. THE CAR SHIFTS ARE HARD TO THE POINT, ONCE YOU COME TO A STOP IT FEELS LIKE THE TRANSMISSION IS GOING TO FALL OUT. *TR
