Thanks for the offer Chuck. I ran one bottle of Techron through the system a couple of weeks ago. This is a car that has been used very little over the past fifteen years, so I figured that there was a good chance some things might be gummed up. However, I've been pleasantly surprised to see that so far there haven't been any real issues due to lack of use.

When you do the injectors, do you set the pressures too? I think I recall reading somewhere that the injector pressures are supposed to be within 5psi of each other.

Just started the car. It always starts fine and keeps running, but remains a little rougher than I think it should be. Seems like the rpm's are higher than they should be too, although the tach shows it at 700rpm's.

On another note, when I installed the new plugs, I set them at 0.038" rather than the book number of 0.032".
