NHTSA Complaint #10455741 — 2007 FORD TAURUS

I HAVE ALREADY HAD THE THROTTLE BODY REPLACED 3 TIMES ON MY VEHICLE. IT LOPE, HEADLIGHTS DIM/BRIGHT, AND JUTTS. ALSO SLIGHT UNEXPLAINED ACCELERATION OCCURS, AND OCCASIONAL HESITATION ON ACCELERATION. FUEL FILTER REPLACED, FUEL PUMP CHECKED OUT WORKING PROPERLY, AND INJECTORS ARE RUNNING FINE. ALSO ALTERNATOR CHECKED OUT GOOD, NEW SPARK PLUGS, WIRES WORKING FINE, NEW BATTERY. MECHANIC CANNOT FIND ANYTHING WRONG WITH THE CAR, BUT IT RUNS TERRIBLY. IT`S LOPED SINCE AROUND 60K MILES, AND SEEMS TO BE STEADILY GETTING WORSE. ALSO ON THIRD RADIATOR. A FRIEND TOLD ME IT COULD BE THE AC GETTING LOW OR CHARGING, OR POSSIBLE IAC MOTOR GOING OUT, BUT THERE`S NO REAL GOOD WAY OF TESTING IT. DEALERS KEEP TELLING ME THEY WON`T FIX UNLESS IT`S FOR SURE BROKEN. WILL TAKE TILL I`M STRANDED TILL A MECHANIC WILL FIX THE PROBLEM.
