Had some funny effects going on with the car.
On a couple of occasions the idle has been high – 1100rpm rather than 850 rpm.
Then when the gt was driving it the check engien light came on. All else was fien so she brought it home.
Flash code analysis showed that 5 flashes was the “throttle position sensor”.
I disconnected the battery overnight, reconnnecated, and the car is fine.
First drive it took a while to re-learn boost, which I noticed on a 2nd gear overtake, but it quickly started boosting through the red after some spirited driving.
Shall get WMSS to check the car, but seems ok for now…
