Pt cruiser jerks when acclerating, hesitates when not accelerating, fine when idle
I am not saying this is the solution or this is the problem but the PT cruiser suffer from code P0344 Which is the cam position sensor which causes misfire, the solution is a reflash of the ECM.But before a reflash the Camshaft postion sensor needs to be verified for working condition and if possible duplicated.Once the Check Engine light does come on you automatically go to limp home mode, This is the drag that you experience,the purpose is to protect the catalytic,in case there was a true condition with intermittent cam postion sensor,You need the check engine light code, then you can go from there.
