Hi,
I have a 2008 Model Thunderbird AVL350 , i have driven this about for 65k. Recently i am facing a misfiring (odd thump/ Pulling back) problem in the engine. When i raise the vehicle rpm more that 2k the engine will start misfiring or it gives an odd thump sound or a feeling like the vehicle is pulled back whatever we call it. I have given it to my regular mechanic and he said it is an electric problem and he changed the pick up coil, main coil and battery and etc. nothing worked out and the problem remains the same. if any body has any idea about this issue, pls share.
