99 chevy s-10 with 120,000 miles. 10 days ago changed plugs and wires. dumped in some fuel injection cleaner. Ran great for a week. Few days ago i drove to work and ran just like new. At lunch time i turn the key and it feels like it's running off of 2 or 3 cylinders. Instant problem. So i have it towed the the auto hobby center on base and replace some vacuum hose. And still problem. Have checked plugs and wires. Wires are tight on the plugs and on the Coil pack. ran code machine thingy and got a p0200. Injector Circuit Malfunction. Need help. what should i do next?
