When was the last service done? did you check/ replace the plugs? I suspect it could be a firing system problem. Lakini a computer check should help you better.

this is true, but have a diagnostic. b14 tends to have aeroflow issues but it is [sp] sortable.

This is fuel related. Have ur mech check the fuel lines and fuel pump. Most likely the injectors are clogged so if you like DIY enda motor boutique ununue injector cleaner

@ jhonie, I am no expert but you may need to have your cars Mass Air Flow Sensor checked/cleaned, may be dirty/contaminated thus affecting the air-fuel mixture, leading to loss of power and shaking.
