I have a 1993 Buick Century with 3.3L V6. Runs fine and gets great
(27mpg). However, it has idled rough as long as I have
had it. I have had the
fuel injectors cleaned twice in the last
year, which helped only slightly. I
have also taken it to 2
different Buick dealers who have told me that the 3.3L
idles rough, and there is really nothing that can be done about it.
It's hard for me to believe that rough idle is normal for a mid-size
Does anyone have any additional information?
