Hey, just wanted to thank everyone here, especially Swart, Blaze, and Dave.
Just finished a tune up on my Wife's 2000 Blazer, 2wd, 4.3, 125,000 miles, after having to replace the Intake Manifold Gasket.
Y'all have been a great deal of help and it would have taken much longer without your willingness to share your experience!
I owe y'all a beer, if we ever run across each other!
Thanks again,
Big D. In S.C.
