I have replaced the spark plugs. Should I replace the coil pack or the spark plug wires? Or what else could it be. It seems to miss when you steo down on the gas. It seems like it does it more when it is warm.

Thank you

Replace the wires and see if that solves the problem.

If that isnt it have the ignition module and coil checked.

If you have a coil pack, change it. If you have cop's it can be a split boot on one or more.
