P0172 system too rich bank 1. P0300 random multiple misfire. All are a common symptom of either bad fuel pressure regulator or leaking injector. Need to pull off intake plenum (upper) You should visibly see a clean side or part of intake manifold (lack of carbon buildup) Reconnect fuel lines. Energize fuel pump (turn on key to run) Most likely you will see fuel dripping out of rear (fuel pressure regulator) or nylon lines to each cylinder (fuel injectors). Once you see which is leaking will need to replace. Once they are repaired will need to clean or replace spark plugs & change oil & filter.
