Yes this could definately be the problem .. re-attach the wire.

You really need to have the car plugged into a diagnostic scanner to retrieve the fault codes, this will tell us where the fault lies ..it could be any number of sensors/parts causing this symptom, repost with full fault codes for further assistance and repair information !
