Same as you dinoquad.Me au2 started to miss and wobble on take off,idled fine ,ran fine but put into gear it would play up.Changed the usual suspects,plugs,leads.coil,well the local experienced mechanics did.Then they were saying maybe dirty injectors ,maybe fuel reg.I asked did they check the inlet manifold.All good they said. So I rang the ford wreckers to recommend me a good ford mechanic.Anywho new gasket and it runs like new. took 3 mechanics.3 days without car to get something that turned out fairly simple to fix
