Good to hear spark plugs have been changed.

At 90,000 miles and 24 years, the wires are likely due as well.

Another thought while I'm thinking about it: What make and model of spark plugs were used?

I still cant figure out why this problem only occurs during the months when the outdoor temperature is above 70 F and not in the winter
months.

I wonder if this could be a coil related issue.
During warm days when the car is acting up has anyone used a good shop scanner to record/ look at live data while driving ?

Soft Ride.... Do you think if I removed the ICM and used some Thermal Paste or Thermal Grease on the underside it would help??

Has anyone else with the 3800 Series II engine run into this problem or is it only unique to my park avenue??

If the major grounds have not been cleaned I would suggest doing that.
