P0204???

[anthony91stang]

I have had P0201 thrown before and all I had to do was unplug and plug back in the harness on the injector going to cylinder one. That solved the problem. I did the same on the injector harness going to cylinder 4 and it solves the problem until the car warms up again. The car really starts running rough and idling rough after getting warm. What can be causing this? Thank you in advance for your response.

The causes of a P0204 engine light code could be any of the following:

Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
Open in the wiring to the injector
Short in the wiring to the injector
Bad PCM

How would I figure out which one of the following issues it has? I'm thinking I may need to take it to a shop...
