Ive been chasing down an intermittent P0200 code for a couple months now.
The car would drive fine one day, then the next it would have a bad missfire and hesitation. It was on and off, and would only set the code every once in a while. I tested the coil packs, changed the plugs, ohmed the plug wires, cleaned the injectors, checked through the wiring harness, nothing helped.
Earlier today I was screwing with it and noticed that stupid rubber grommet that holds the PCV valve was loose. I removed that grommet all together and replaced the PCV valve with a different style that has a fitting one side and the other side is threaded. That made a nice tight seal on both sides. As soon as I did that the car ran perfect.
Thats my experience, hope that helps anyone having similar problems.
