Jar Jerks When I Boost

[starletdave]

hello all ..im using a ep82....recently i encountered this new problem ....whenever i slam my fuel pedal ..the car jerks vigorusely.....but if i gradually do it .then its fine ..but i still feel little little pulling...like something is stopping the fuel

earlier i thot it was my fuel pump faulty ..so i replaced it...it worked fine for a week ...then it started again ...so i replace my fuel filter.....1 week ok ..and then again its back ...im also running on e adjustable fuel regulator...can anyone help me on this...??
