I have a 1996 4.3 L, 5 speed chevy s-10. The problem I'm having is the engine surges (feels like one cylinder misses every 20 seconds) every morning for the first 15 miles at highway speeds then it's fine. You can really feel it when I'm going through the gears. I've replaced (with all ac delco parts) the sparkplugs, wires, cap, rotor, ignition module, and coil. I had the module checked before I changed it and it did show a fault. I'm now left thinking it's a injector. Any ideas?
Thanks,
Brian
