Q: Q: Car just idles

asked by on

The car starts but does not accelerate. It just idles.

Hi. I believe the issue your having is a result from a faulty throttle position sensor(TPS). The TPS is electronic and should move the throttle plate in sequence with the gas pedal. If the TPS is malfunctioning, the sequence will be off and a lack of acceleration could occur. I suggest that a technician tests the TPS with a scan tool or multimeter to determine if it is faulty.
