One problem related to car stall has been reported for the 1998 Toyota Corolla. The most recently reported issues are listed below.
This complaint is about a gps device that attaches to the car through the obdii port. Manufacturered by agnik corporation sold under the brand name vyncs. The device, when installed, has caused intermittent stalling of the vehicle at low speed such approaching a stop or idling in gear at a stop. This was realized to be caused by the device after about 1 week of experiencing intermittent stalling. When the device was removed from the car, the stalling issue dissapeared. I have retained the device for submission to the NHTSA for testing. When I brought this issue to the manufacturer attention they ceased communication with me, disabled the gps service, and closed my account, whereby I could no longer extract any historical communications from them. Additional attempts to contact them through techsupport@agnik. Com have been unanswered. Agnik does not publish an address or phone number.
