HOI!My Mondeo St200 starts jerk when accelerate fast. Usually when drive 2,3,4,5 gear and accelerate. First of all, I think it's a fuel pump problem because I'm driving a mk1 V6 2.5 fuel pump. Now I have changed the fuel pump. Also changed spark plugs (NGK), fuel filter, close the EGR valve. My local mechanic connects to Pc and deletes some MAF errors, but nothing changes. So maybe someone has similar problems? Maybe the reason is spark plug wires, coil pack, or fuel pressure regulator?
