When engine is started, both when cold and hot, in all gear selector positions, and an attempt is made to depress the accelerator pedal, the pedal will nor depress normally. To depress the pedal, a moderate force is required. When this is done, the pedal linkage then makes a "snapping sound" and the pedal then advances suddenly, causing the engine RPM to race. If the car is in any gear when this is done (drive or reverse), the vehicle will then either lurch forward or in reverse. The dealer serviced this problem for the first time on feb 6, 1999, at which time they diagnosed the cause as foreign material and replaced the j5490 body unit, throttle. This solved the problem for approximately one month. In march 1999, the condition reappeared, and the dealer replaced the j5330 cable, accelerator control.
