My peugeout 207's ignition coil pack is registering as faulty, would that explain a loss of power. The problem started over a year ago when the power loss was only on start up, now, however it happens more regularly and a DPS fault has registered on the car's computer. Many of the forums have said that replacing the coil pack does not necessarily solve the problem. The mechanic said that the ignition coil pack fault was the only fault that showed up on diagnostics
