Have a weird problem and not knowing much about motors im stuck.
I filled up yesterday at my local Jet station and since then ive had a problem.
When I accelerate all is fine until I hit 3,000rpm when it then starts to back off on the power, but then picks up again at 4,500rpm.
Could it be dodgey fuel or am I looking at something else? It sometimes stutters as its accelerating through 3,000 too.
Thanks
EDIT: Oh, and its only done 30,000 miles and just had a service in December.
