Change your sparkplug wires! It cut all my hesitation at idle problem. My car idles perfect now, as if it was new. I guess the wires dont last that long. Mine were out by 96k miles.

Ohm readings
If you still have the old wires, I'd love to hear what the resistance readings are for the old wires (ohms). I'm just wondering if it's a gradual degradation for all the wires or if it was only one or two wires that were causing the problem. I'm in the same boat as you and was wondering about a full replacement, but it's a bit expensive, so I'm trying to use my brain here and use an ohm meter to make an educated decision. Thanks in advance.... Paul

I changed mine last year to the Magnecor 8.0 mm wires and NGK irriduim plugs. It made a big difference in engine response and made it run smoother. I believe Magnecor posts there resistance numbers on their website.
