Had an issue with the 03 wrx a few days ago. It was running perfect no problems 0.9bar boost, no issue. Then suddenly while on a drive it suddenly fell to 0.5 bar. I pulled in shortly after, turned the car off, let it sit for a few minutes, switched back on and it ran perfect for the rest of the journey. Then I took it out the other evening, ran perfect for a while and then same issue again although shutting it off didn't resolve the issue.
I had put petrol in, from a fairly new Topaz Miles fuel pump about 30 minutes prior to the first incident. Possibly bad fuel? Or else a knock sensor on the way out?
It's also an Irish car.
