[Ben135i]

Today while driving my 135, Under hard acceleration above 3000 rpm the car started to make some sound strange noises and instead of a very fluid and constant acceleration it was abit jerky, and then before finishing the gear the engine light came on and any acceleration what so ever resulted in the entire car shuddering and very little power, the noise it makes sounds like a deep whooshing mixed with a thumping kind of noise (hard to explain), then I pulled over and turned the car off and then back on, the car was normal again, now if i lightly accelerate I can go all the way through the rev range no problem, but as soon as I go full throttle over 3000 rpm the problem returns...!! Any ideas???
