Engine stall and backfire
My 350 vortec 1992 starts up on, idles rough on all
8 cylinders but when I try to drive off or rev it up, it
will pop through the tbi, but if I put my foot in it
hard, it revs . When I try to drive of normal it with
pop, , sputter, and start to blow black smoke
(loading up). But if I but! For in it hard it will break
the rear wheels lose and fun beautiful until I ease ,
than runs rough. New cap, rotor, plugs, wires. Any
ideas? Any advice will be appreciated. Thank you!
