    I recently posted how my brother and I couldn't start up this old 85 2.8 blazer, but we finally got it to start last night!!!:D(thanx for all your help btw)...And it ran very good for all the warm up stuff, and I even drove it around the block without incident. This afternoon I pulled it out of the driveway and it died right when I hit the street (Steep Driveway). After that it started to behave weaker, doesn't really want to accelerate, and even makes sputtering sounds right after reving it. Would anyone have any ideas about this problem??:confused:

    -Thanx alot in advance for any help?
