Still, the kit does seem to solve the driveability problems seen on some SCPI stockers. In fact, GM does not even service the injectors separately. However, these injectors are still not a standard direct-port fuel injector configuration, so they cannot be upgraded with higher-capacity units. The kit moves the injectors out of the original fuel meter, relocating them downstream in place of the troublesome poppet valves. Also required is a seal kit, upper-to-lower intake (PN 17113206), and a new fuel meter body bracket (PN 93442096). According to Burt Chevrolet, GM finally issued a service MFI (multiport flexible injection) kit (PN 93441235) that includes a new fuel meter body, a regulator, eight drivers, eight Multec-2-style injectors, electrical connectors, and lines to connect the drivers in the fuel meter body to the injectors. Initially, GM recommended an injector-cleaning process, but it was only a temporary fix-eventually the problem would recur. The problem was usually most apparent under cold start-up conditions after sitting overnight. Deposit buildup on the valve's ball and seat would cause the valve to stick open or closed, resulting in a misfueled cylinder and consequent misfire. The original SCPI poppet valves proved problematic.
