Pommy Posted April 10, 2014 Share Posted April 10, 2014 I had similar issues which ended up being a spark plug, would rev perfectly without any load but then when accelerating hard it would hesitate and judder. Quote Link to comment Share on other sites More sharing options...
Gambit Posted April 11, 2014 Share Posted April 11, 2014 I would say the same as pommy or a failing coil pack if you check your codes you might find it's got a misfire code. I'f also check for any split or damaged pipes on the intake. Quote Link to comment Share on other sites More sharing options...
