coil pack spark. Basically My car is down 80 hp because I think the old lifters have ground the lobes on the cam. However, Last night I noticed after unplugging the coil packs one at a time.. that the 2nd coil pack on the driver side sparks at idle. None of the other coild packs do this. I changed the coil pack and the same thing happens. Is there a reason for this. I'm checking ignition parts because my hp tuners shows low reading on bank one.
