Yes what does code P0204 Injector Circuit Malfunction Cylinder 4 mean? What would have to do to fix it? It started jumping and shaking about 15-20 minutes after I filled my truck up & check engine light came on. Thank You

If its bad gas you would see more than one cylinder misfire
I wouldn’t put it off
I’ll still check the fuel
but its an injector problem
1st check if that injector is pulsing if so the injector no good

unplug it use a light check if it flash with engine running
they sell a tester for it
its like a small light plugs in instead of the injector

You can check the resistance of the injector using an ohm meter. With the injector unplugged check the resistance across the injector it shouldn't be more than 12 ohms. Also check the terminals in the injector connector and make sure they are not spred. I doubt your gas fill up has anything to do with your problem becuase this code if for electrical integrity of the circuit.
