HAVE HAD RECURRENT PROBLEMS WITH ENGINE PERFORMANCE IDLE AND RUNNING. ENGINE RACING WITH RPM'S TO 3500 AT STOP SIGN. HAVE HAD TO TURN VEHICLE OFF TO RESOLVE PROBLEM. I WAS AFRAID THAT IF I DID NOT TURN ENGINE OFF, IDLE WOULD HAVE CONTINUED TO RACE AND "BLOW UP." ENGINE ALSO HAS VERY ROUGH IDLE/ALTERNATING WITH INTERMITTENT MISFIRES MOST OF THE TIME... "BOGGING" DOWN TO ALMOST STALL /THEN RACING TO RPM OF 1500-2500. THIS PROBLEM OCCURS WHEN ATTEMPTING ACCELERATION ONTO FREEWAY OR WHEN DRIVING AROUND TOWN AT SIGNALS. VEHICLE HAS BEEN TO DEALER 4 TIMES NOW IN ATTEMPTS TO CORRECT MALFUNCTIONS. I AM CONCERNED THAT THE OPERATION OF THIS VEHICLE IS UNSAFE. THE DEALER HAS BEEN HELPFUL BUT UNABLE TO COMPLETELY RESOLVE THE PROBLEM. THE MANUFACTURER INSISTS THAT PROBLEM WILL BE RESOLVED, BUT I, THE CONSUMER BELIEVE THAT THE VEHICLE IS UNSAFE AND UNRELIABLE. IT IS ALSO TIME CONSUMING TO REPEATEDLY RETURN THE CAR FOR SERVICE. *LA
