The EGR will not cause this issue, this sounds like the Catalytic Converter was not hot enough, another trick that worked for this kind of fail was a fresh oil change, make sure the engine is up to normal operating temp, which would be just short of 1/2 scale on the temp guage, if it runs cold replace the thermostat, I did smog tests for 30 years and these are the things I did to get cars like yours to pass given the test results you gave for the tailpipe.

An intake gasket vacuum leak can cause this also. Sometimes you can isolate the problem by spraying carburetor cleaner at the head/intake mating surface while the engine is running. The fluid will cause a momentary stable idle when you find the right spot by plugging the leak. Could be a leaking vacuum hose too.

Bank 1 o2 sensor 1999 honda accord lx v6, i need the location to change it. i can not find it in the front of my car


Bank 1 is at the back of the engine compartment next to the firewall. You'll need to know if you need to change (bank 1 sensor 1), or (bank1 sensor2). Sensor 1 is located in the exhaust system between the rear cylinder head and the catalytic converter. Sensor 2 is after the cat in the exhaust system after the cat.

I Have a 1993 honda accord ex.Just Changed the valve cover gasket! Checked the plug wires recently and the had oil all over them.What is the Problem?


When you changed the valve cover gasket, did you also change the seals that go around the spark plug holes? If you did,and theres still oil getting in there, they might have moved when you installed them. If thats the case, hold the seals in place with some RTV black sealant and try it again.

Flashing green s on the dash


A green flashing "S" is similar to a check engine light. It is telling you that something in or on your transmission is not functioning correctly, such as the speed sensor or shift control solenoids. If it starts flashing and the speedometer stops working or the transmission shifts weird, take it to a mechanic.
