Hi Dave i had one of these from garage.The coils & plugs already done.This sound the same start engine runs lumpy for 20 second then goes of a cylinder as ecu switches cylinder off.I vacuum test cold & had 2" of mercury, my think was that somthing was wrong with valves/ valve timing.i then spoke to garage to get more info & they told that they had just done a oil & filter change with 10w40 looking at autodata oil should be 0w40 or 5w30 fully synth so flushed & changed oil.Retested vacuum next morning & went from 2" to 10" of mercury engine sounded alot better & did not go off a cylinder & after another minute or so vacuum went to 18" of mercury.This might of been a fluke but this might help.
