Default code 43 help

93 civic, just threw the code this morning. checked fuel filter, no 02 sensor codes, but its about a year old, car runs just fine. no problems whatsoever. i noticed gas pressure dropped from about 40-41ps1 to 36psi just today.

spark plugs looked kinda white, but still had some black on them, so if it is running lean, its not by much.

Did you measure the fuel pressure with the engine running and with the FPR vacuum hose disconnected and pinched?

Im having the same issue with my 94 DX hatchback. Im throwing a code 43, but the car runs fine with no issues whatsoever. If I turn the car off and back on then the code is gone for good, even after a 30 min stop and go drive home.

Check the O2 sensor.
