Replaced ECM/PCM and pressure regulator (Note before replacing parts I disconnected vacuum hose to pressure regulator,car ran fine and no hard start ups) with Honda kit (06161-P8C-A00)/ service bulletin 00-024 for hard starting/run rough after driving a while only. Starts fine cold and any other time after sitting more than an hour. Now every morning check engine light comes on with P1107 (baro. sensor code located inside PCM?) . Seems to run fine and no longer has hard starting after warmed up. Do I have a bad PCM or have other issues.
try to reset the ECM first (see picture below)
