Hi iam new to this forum two days ago i was driving on the highway at about 110km on an incline in fourth and the car started boosting for no reason, it is jerky and only lasts for a couple of seconds and then its fine again. You can hear the blow off valve releasing when it does it
Iam not sure what might be causing it but it feels like the car has a dead spot or something
Does anyone know what might be happing or causing it

Thanks
JR

 

Is there a check engine light? Do you have a boost gauge?
