Having been to Donnington on Sunday and given the car a boot full or so on the track all seemed well and the trip home was fine.

On the way to work on Monday, put my foot down after about usuall 5 mins warm through and was greeted with a mis fire .
This felt and sounded like fuel starvation and did not really clear for several mins when trying to accelerate hard.

After another 5 miles or so business as usuall.
MY98 ramair filter and ss back box 47,000 miles
Any ideas?
Thanks
