Lynn,

Is your Buick the V6 that is port injected and has DIS ignition??  If so you
may want to try replacing the DIS module which is the module that is what the
coils are mounted to.  As far as the rough idle, has anyone checked out the
injectors yet?  You may have a fouled injector, or possibly a vacuum leak.
Your 10"hg sounds low for this engine, it should be around 15-18"hg when its
idling smooth.

I was a GM tune up mechanic for many years, and we had many problems with the
early 88 DIS modules.
