UPDATE: New plug wires and plugs were added and made a significant improvement. The parts place sent the wrong rotor so we'll have to wait until next weekend to replace it.

While the hesitation is much less noticeable, it is none-the-less still present. After what I've read so far in the forums, I am beginning to wonder if it might involve a Throttle Position Sensor issue as well.

Next weekend, we'll replace the rotor and recheck timing and such. I will keep you posted as to progress.

Don't miss the forest for the trees.
