Could be any of those, or an air leak in the bellows area, or the DME realy on the nearside wing. But I'm no expert the Guru Brian will be along shortly!! :wink:

Sounds like a leak between the AFM and the TB TBH.

sounds like it needs an "italian tune" (that's 110+ on the motorway for 5miles...)

stuttering is likely to be down to a leak as widge said.

check all the boots on the afm for cracks or leaks

also have a quick look at the rotor arm for deposits and give it a clean.

Hehe, funny that! Because thats exactly how I cleared my motor out (well, was between 95-100mph) Can't do anymore without it sounding like its gonna blow!

Alas, the problem is recurring...............here comes the conversion!!!
