Greetings all.

Had this problem for a while but finally was able to capture it on vidya.

Whenever i come to a stop at the lights or after a brief acceleration in carparks (such as in the video) the revs will randomly "pulse" so to speak where they climb and then just as quick they drop to the point of the car stalling, then it repeates the process over and over till after anywhere from a min to roughly 4 mins it calms down into a propper idle.

Had alot of wierd looks as the car is loud so it appears as though im sitting at the lights revving the car ready for a race, Click here to enlarge

here is a video of the event, for the first few seconds i accelerate through the opening in the carpark, then the "pulsing" starts



any help is greatly appreciated.

And no error codes with obd2 reader or stomp test come up.
