re: 1997 blazer 4.3 l
Hi ok to my understanding monopoint is a single injector in the throttle body or you will have 1 per cylinder in the manifold with spider wires running to them, 1 per cylinder is multiport, as far as 02 sensors most have 1 but you may have 2, 1 per side on the exhaust manifold or the pipe right after TROY
