89 Blazer 4.3L TBI Rough idle and skip under acceleration
My 89 Blazer idles really rough and shaky, and when I accelerate I can tell it isnt running right. I just want some tips to make it idle and run a little smoother.

I have an old 91 S-10 4.3 (230,000) and I took the TBI off and the TBI had a large amount of gunk on the bottom side and some of the ports were completely clogged. It took two cans of carb cleaner but it def helped it run better. Make sure you disconnect the battery before removing the TBI setup. You can also check all the vacum hoses at the same time.
