2000 Honda Accord

Dear Doctor: I have a 2000 Honda Accord V-6 with 76,075 miles. A year ago, when driving for long periods of time, then shutting off the engine for a couple of seconds it wouldn’t start and the “check engine” light was on. I went to Auto Zone and changed the EGR valve and cleaned the fuel injector. Now, the same codes are appearing again: PO300, PO301, PO302, PO303, PO304, PO305, PO306, P1399. What should I do? Vibert

Dear Vibert: All these codes indicate an engine misfire. The most common cause on the Accord is a sticking EGR valve. When the EGR does not close fully, it causes a lean condition (too much air), leading to a misfire. Take your car to a qualified technician and have him check it with the proper scan tool to observe the EGR valve operation. I see a lot of these V-6 engines with EGR problems. We remove the intake and clean all the carbon deposits.
