You need a scan tool attached to the 16 pin diagnostic port under the dash to determine what trouble codes are stored in the computer in your car. The codes will indicate what area to look at. You will probably find an ignition coil or spark plug failure of an injector issue causing a misfire under load.
Hello you should have the computer scaned by connecting a OBDII scan tool to your 16 pin on-board port and this will get you the fault codes as Hal has stated if there is a AUTOZONE near your area they will scan your vehicle for no charge and this will get you to the system that is having the problem.The most common failures are the ignition coils and the spark plug wires,etc.HAVE A BLESS DAY from DR.RECO.
