Then i would start looking at the plug leads . Just wondering does it do it from cold when you start up or when the engine gets hot . I have found that plug leads and coils if there is a problem with them start to break down when they get hot its happened to me more than once so try starting up from cold give it a bit of pedal and see does it hesitate from cold i bet it doesnt
