2004 Nissan Sentra Speed Control & Cruise Problems

I WAS DRIVING DOWN THE INTERSTATE, AT 60 MPH AND THE ENGINE DROPPED TO 700 RPM AND REFUSED TO ACCELERATE. I HAD TO PULL OVER, SHUT OFF CAR AND REPEATEDLY ATTEMPT TO START CAR. THIS HAS HAPPENED 8 OTHER TIMES IN THE PAST MONTH. *TR

TL*THE CONTACT OWNS A 2004 NISSAN SENTRA. WHILE DRIVING 65 MPH WITH THE VEHICLE SPEED CONTROL ON THE THROTTLE SLOWED DOWN AND THE VEHICLE WAS UNRESPONSIVE. THE VEHICLE WAS DRIVEN ONTO THE SIDE OF THE ROAD, THE ENGINE WAS TURNED OFF FOR AN HOUR, THE VEHICLE WAS RESTARTED AND BEGAN TO DRIVE NORMALLY. THE CHECK ENGINE LIGHT ILLUMINATED CONTINUOUSLY. THE ECM AND THE ELECTRONIC THROTTLE BODY CONTROL WAS REPLACED BY THE DEALER AT COST TO HER APPROXIMATELY TWO YEARS AGO. SHE DOES NOT KNOW IF THIS CAUSE THE VEHICLE SPEED CONTROL FAILURE TO RECUR. THE VEHICLE WILL NOT BE TAKEN TO THE DEALER. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 141,000.

THE CAR IS ACCELERATING WHEN BRAKES ARE APPLIED TO STOP. IT DID IT ONCE LAST YEAR AND 3 TIMES THIS YEAR WITH IT BECOMING MORE FREQUENT. IT HAS OCCURRED TWICE IN THE LAST 2 MONTHS WITH 8/20/2010 BEING THE LAST TIME IT OCCURRED. *TR

CAR HAS NO ACCELERATION. WILL NOT REV OVER 900 RPM. WHILE DRIVING LOST POWER BUT ENGINE KEPT RUNNING FINE. IT ACTED LIKE CABLE BROKE ON THE PEDDLE. BUT TO FIND OUT IT IS ALL ELECTRONIC. WAS ABLE TO GET OFF ROAD BUT WAS ONLY ABLE TO GO 10 MPH IN TRAFFIC. *TR

I JUST WANT TO ADD A REPORT OF (SO-CALLED) SUDDEN ACCELERATION SYNDROME THAT OCCURRED TO ME ON THANKSGIVING DAY OF NOVEMBER 2007 THEN AGAIN WITHIN A MONTH OR TWO AFTER THE NISSAN DEALER SAID IT WAS DUE TO A BADLY POSITIONED FLOOR MAT. THE SECOND TIME IT HAPPENED, THE DEALER SAID IT WAS A "DIRTY THROTTLE" THAT REQUIRED $75 "THROTTLE SERVICE," -- A CLEANING -- TO WHICH I READILY CONSENTED. THE ACCELERATION PROBLEM HASN'T REOCCURRED (KNOCK ON WOOD). IN BOTH INSTANCES, THE CAR SPED FORWARD WHEN MY FOOT WAS OFF THE BRAKE SO QUICKLY I BARELY HAD TIME TO REACT. FORTUNATELY, I DID NOT HAVE AN ACCIDENT OR CAUSE ONE. I DRIVE A 2004 NISSAN SENTRA, WHICH I MAINTAIN REGULARLY. THE NISSAN MANUAL STATES THAT THROTTLE SERVICE SHOULD BE REGULARLY PERFORMED (SOMETHING I HAD NEVER HEARD OF BEFORE) BUT NOT THAT NEGLECTING TO DO SO COULD CAUSE THE CAR TO ACCELERATE SUDDENLY. THIS WAS NOT MILD ACCELERATION -- THE SPEED INCREASED ALARMINGLY UNTIL I PUT THE CAR IN NEUTRAL THEN HIT BRAKES (I INSTINCTIVELY TRIED BRAKING FIRST, WHICH CAUSED THE ENGINE TO RACE) AND PULLED OVER TO COLLECT MYSELF. THIS ISN'T EASY WITH POWER STEERING. *TR
