does it have any patterns, i.e is it when its hot or cold?every car tends to have some pattern to its faults and it can help to solve it.you say youve had it on a diagnostic and it shows no fault codes at all? you say it feels like fuel starvation so its most likely a fault in the fuel injection system.it every car can be fixed so dont worry.1st i want you to check the vacuum pipe on the injection system,its 70cm long and only 2mm internal diameter so you should be able to find it easily,check for any leaks and blockages.also how good are you with a multimeter?also have you put any fuel injection cleaner in it and has the fuel filter been replaced ,its worth doing the easy jobs 1st and it will help it to run better anyway.you said something about coils,are you meaning ignition coils ?if so that should have registerd on a diagnostic.also just want to be sure the air filter and plugs have been changed.if you have a friend or family member that knows basic mechanics i will be able to cover all possibilities.
