MY 2005 FORD FOCUS IDLES ROUGH BUT RUNS GREAT AT ALL OTHER TIMES. I HAVE REPLACED THE RIGHT FRONT MOTOR MOUNT, TPS VALVE AND THE IDLE AIR CONTROLL VALVE. THE REASON THAT I HAD REPLACED THE RF MOTOR MOUNT WAS BECAUSE I HAD A SIMILAR VIBRATION AND THAT CURED IT. NOW IT IS 1200 MILES LATER AND I'M HAVING WHAT APPEARS TO BE A VERY SIMILAR VIBRATION AGAIN.
THANKS, DICK
