09 GTX 255 stalls under hard acceleration
I'm new to this forum and want to say hi first off.
I just purchased the 09 GTX and a 12 GTI SE 130.
When riding the 09, It will stall out and drop the rpm to around 3k when you reach rpms around 8k but it will not die. You just wait a few seconds and it goes back to running fine unless you go hard on the throttle or reach the 8 k rpm range. Does anyone have any clue what it might be. I took it in to have it serviced and changed sparked plugs. I would greatly appreciate any advice.
