      I recently repaired the valve cover gaskets. I got it all back together and ....

      P0201 - Fuel injector circuit condition - #1
      P0205 - Fuel injector circuit condition - #5
      P0171 - Fuel trim bank 1 / Bank 1 lean (probably a child code related to above)

      Has anyone seen this issue before? I suspect an electrical issue with the #1 #5 fuel injectors which I had to disconnect to remove the valve cover.

      Its running "OK" but certainly not as well as before the repair. Rough idle, less giddy-up.

      Thanks to anyone who can help.

      I had P1131 and P1151 and only once P0201/0171. Maybe the electrical connector didn't reconnect properly? In mine, it went away after a reset and only 1131 and 1151 remained which turned out to be leaky gaskets or EGR valve.

      The folks at the local parts store were gracious enough to let me reset the codes. They came right back after the second time I cranked it up. I will check the connections on the fuel injectors.

      Got in and jiggled the appropriate fuel injector electrical connections and the problem went away. No codes, running great.
