Default Truck misses with code PO200 but goes away sometimes

I've read that it could be anything from a loose/pinched wire to a bad PCM. It comes and goes. Sometimes I can get rid of it by flooring it for about 5 secs. I've tried wiggling some cables but still nothing. Anyone have any experiance with this?

That is an injector control circuit code. No experience with it, but nevertheless an odd code. Have you done any work on the injectors? Replaced intake manifold, something where you may have cause a loose wire or short in the injector harnesses and/or clips?

When it is acting up, ohm test each injector. You may have an injector failing electrically.

It happens almost all the time. When it is missing, I can get rid of it by flooring the throttle to redline a few times. Kinda weird. I will try and check the injectors when I get the chance. thanks for the suggestion

Well, I ohmed out every injector and all were pretty close to 12.8. I hooked everything back up and havent had a problem for the last 4 days. I guess there was a loose wire
