do my very best to assist you with your question today.

Engine managment light is on at the moment but this was hapening before this light came on.


the car is running perfect plenty of power no other problem only on tick over you have this hunting.


could there be a sensor faulty.

Expert:  Mike Kelly replied 4 years ago.
Hi from what you are describing there is a crankshaft sensor that is causing the issue that you are currently having. The system is detecting a fault with the sensor on start up. As a first step I would suggest having the vehicle scanned for trouble codes.
