Well, I cleaned everyplace where there would be a loss in contact due to the wicking of the protectant. This included all spark plug wire connections and grounds as per the troubleshooting guide from this site. Still nada. Finally opened the coil plastic cover and cleaned, using alcohol, the connections there. Fired right up. Runs great and starts everytime. I really don't know why the tech felt he had to use that junk on the engine and will insist on not applying in the future. The shop is really good and the staff knowledgeable but this was a real snafu if you ask me.
Thanks to all that replied and Fishcop and jeff were right on with the electrical issue. At least I know the DME relay that has sat in the trunk works great and will keep the other now as a spare.
As an aside, the hesitation that I was experiencing for the the last three years is now gone. The culprit was most certainly the head temp sensor. The tech said the old one was loose and replaced it with one that came with the car (two wire upgrade). The car runs better than it has since I bought it!
