If the car only seems to miss during a heavy load the problem could be the wires instead of the plug. Sometimes if the boot is slightly seperated from the wire it will act that way. Try revving up the car in the garage without the lights on, and you may be able to see light coming from where the boot and wire meet near the block. The wires are, of course, relatively easy to change, so you may want to think about changing those with the cap and rotor. Good luck
