Hi Guys, recently my car starts to jerk a little once it touches 3000rpm and stops at 4000rpm. This happens especially in the morning and also when say u are crusing at a constant speed and u step a bit more gas suddenly. Doesnt matter which gear u are on so long as it touches that range it will start to jerk a bit. If I were to do a launch, I realise there no jerking at all. Don't think its the boost cut because u don't have to put your foot down all the way to have the jerking. And it's not misfiring for sure coz I just changed my plugs and regapped to 0.8. My fuel pump works fine and injectors too I think, if not the jerking might be everywhere when I push the motor. Wondering if any of u guys had this problem before or any of u can help.
