    93 Accord maintenance and diag..

    My GF just bought at 93 4DR 4 cyl, auto with 160K that has obviously been neglected for who knows how long. The 18 year old we bought it from didn't know much of anything about anything, the PO before him wrote the T-belt had been changed at 73k on the inner fender well.

    After buying it and looking into it more so I found alot to do. Looked to have original plug wires, tube seals were puking, bypassed power window relay, distributor o-ring and inner seal leaking, needed 2 tires & alignment possibly front end components, severely cracked drive belts, flashing D4 light.

    I've changed the plug, wires, dizzy cap n rotor, valve cover gasket, fuel filter, burned some seafoam through the intake and added some to the tank, also checked the codes. There was a CEL #43 with no CEL on when running, from looking at the code def on this sight it's a fuel delivery issue, the D4 light is a #2 which is the lock up shift solenoid, also info I've read here

    After changing the valve cover gasket and the tune up a cold start issue started. After holding the gas pedal down for a few minutes every morning the motor will hold idle and start normally the rest of the day, pretty weird..

    Sorry for the long post. This is my first Honda experience

    The Code 43 is more likely an o2 sensor issue. Not sure why a bad o2 sensor sets that off, but I've only seen one instance of it actually being a fuel system issue.
    Pick up a Denso or NTK sensor (cheap on rockauto.com) to replace what you have. Don't get a Bosch sensor, as they never work properly. Most autoparts stores will give you Bosch by default.

      according to the counterman at alot of stores, Bosch is the best thing since sliced bread

      stick with what Deev said

        I replaced mine with a bosch and it still would give me problems so i bought a denso one and held up pretty good.

          Bosch made the first o2 sensor, I believe. They make good products... just not for our cars!

            IMO bosch works better for domestics then imports

                    That was the answer to your question, not your unrelated pictures.

                      I've read some things about the main relay under the dash having problems and causing intermittent starting issue but from the symptoms I've seen none relate to mine. Not really trying to throw parts at it though

                        That seems like a rather unfounded thing to say.
                        My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!

                          Checked to make sure the fuel pump is priming by listening at the filler neck with the gas cap while my girl turned the key to the on position and it is priming, so there has to be some problem with something.. hmmmm

                            Well more diag, replaced the drive belts, both battery terminals, no change. Took it for a drive drove pretty much the same but with the new belts the car vibrated alot less as expected, the old ones were shot.

                            After it sitting a few days I went out n played with the idle using the adjusting screw on the throttle body, didn't change anything.

                            Checked the codes again, now a solid CEL is on no flashes. Guessing its time for a new ECM

                              I believe a solid check engine light is a ecu problem.

                              as for the fuel issue maybe try a new fuel filter or it might be a dirty injector.

                              I would also do a timing belt and water pump just to be on the safe side
