I have a trouble code PO204. The thing about this is I took the fuel rail off and cleaned the injectors the other day never seen this code before now. I was very careful I know how to handle delicate items and when I had it all done every thing was fine except the PO204. The car runs good no miss no surging. I even put number four injector in 2 and 2 in 4 but I still have a PO204 I thought it might go to two you know injector problem but no. So does any one have any experience with this. Thankl You

Arse you sure that this is an active code and not a history code, do a code clear and re test to see if it is active, I would expect to see a misfire with this code as active.

I cleared the codes and it came back PO204 but the car runs good I tested the resistance in it and it was good tested the power and signal also good.I have never seen this code it appeared after I had the fuel rail off and I cleaned the injectors. I have been trying to find the vacuum leak but I have not found it yet but you can tell it has one. Thank you

Are you spraying a little starter fluid around the manifold this can help find minor vacuum leaks.
