Trouble code

[graysilverado5.3]

Anyone know what this code is and how to fix it? P0200- Injector Control Circuit.

I was driving the other day and all of a sudden the truck started to shake more than usual and like the truck didn't wana go forward anymore. I took it to my tuner and this was the code that came out. Whenever I drive the truck it feels like it hesitates to move. Any help would be appraciated. Thanks

First thing first check your fuel pressure. Next check and clean your grounds. You could have a fried PCM. Check the grounds at the back of the driver side head. It may be simply water in the fuel. You might add a bottle of HEET to the fuel tank to disipate any water that might be in there.

Does the pcm of my 04 work on his 05?? If they work we can try mine out. both trucks are tuned for the same cam, so driveability should not change much

Use a scan to to monitor CURRENT misfires. If a cylinder is misfiring work on that cylinder. Check connector at injector, wiring harness(shorts or opens). Remove connector on misfiring cylinder. Backprobe the connector to check for voltage with key in KOEO position. Is voltage present? Replace connector and start engine. Backprobe the connector with engine running. Is terminal pulsing? Ck injector resistance value:11.4 ohms. Ck grounds to injectors(clean and tight connection). Check connector at PCM(ECM). Replace injector. This is on overview of the troubleshooting procedure for this DTC, but you get the idea.
