   Hi guys,
   
   I've recently been having a problem where when my car's cold it jolts when driving slowly (due to speed bumps) at about 1,500-2,000 revs in first. It was anoyying but it seems to be getting worse today I was accelerating and the jolting was really bad in second and third.
   
   I found another problem where if i give it a quick squirt of gas bringing the revs up to 1,000 it struggles to idle and keeps going up and down and doesnt stop doing it until i rev the car past 1,500.
   
   Could this be coilpack? Or is it something else?
   
   No EML light and mods are raceland induction kit green filter and a sportex backbox. Serviced not long ago replaced plugs, oil, oil filter and fuel filter.
   
   Cheers guys,

   Try cleaning your ICV 1st mate as myn used to do this at one point.

   Idle isn't bad though only when i give it a bit of gas (by tapping the pedal) does the idle mess up :/. Is it possible that the TPS could cause jolting? Seems like its lost some power aswell.
