Boy you are quick, Steve! The injectors are all brand new, so I've kind of eliminated them. One of the alternative suggestions from my mechanic was to use a good fuel system cleaner in the gas tank and see if that helps. I threw in some Chevron Techron, and it seems to run a little better. What's really aggaravating is to drive my SEC, which starts on the first turn of the starter, and is silky smooth at all rpm's, and then jump into the SL, which suffers in comparison.

Anyway, I'm going to drive it for awhile and see if it gets better. Decided to abandon the switching fuel distributor idea. Thanks again for all the technical and common sense advice.
