Hiya, I've recently had to change out my head gasket and since being rebuilt I seem to have developed a nasty gremlin, I double checked timing during reassembly and haven't really changed anything apart from throttle body (2 wires on original had snapped). After letting the engine get to temp I went for a short spin and found that if I floor it or gently get RPM up over 5k the engine seems to just stall out and I'm fresh out of ideas, I've checked all boots and hoses are connected and am completely stumped, please help Its a 2.0 corrado 9A engine and ran fine before
