SOURCE: How do you clean the EGR valve on a 99' Honda Civic?

Pull vacuum on egr valve with engine idling and see if engine stumbles and tries to die until vacuum is released. If this DOES NOT happen the egr exhaust passage is plugged will need to remove egr valve assembly and remove carbon from passage into cylinder head.

SOURCE: 2000 Honda Accord EGR Valve Error P0401

Jason,
-after you change the part you have to reset/clear the code

-this can be done by either:
(1) using the OBD2 code reader that Autozone used OR since option 2 (below) is very quick
(2) disconnecting the battery for about 30 seconds (this will delete all codes/radio presets/etc) but it will also clear the 'check engine' code
-this is what I do AFTER i write down my radio station presets :)

-hopefully the new EGR valve resolves your issue after you CLEAR the code
...but that code just means a an insufficient amount of Exhaust Gas recirculation (pressure difference) used to keep the emissions in check
-if it comes back, then there are a few other fixes to try also

-let me know if you need further assistance
-please remember to rate me `fix-ya`if it works
thanks

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: Cylinder Misfires

It could be your spark plugs or a coil. To see if it's a coil move the coil from #5 to #6 the miss will change to that cylinder with code p0306 and change #1 to #3 and see if it changes to p0303. If it does replace all the coils. You change all coil because if one or two go you know the rest are not far behind

Im working with a 2006 mini cooper and engine light comes w po304 code the car runs fine no misfire at all,plugs r new


Code P0304 Indicates a misfire in cylinder 4. The computer will notice these long before they get bad enough for the driver to notice. Check your plugs and plug wires for thightness. I know from expierence that "New" parts does not mean "Good" parts.

If you have access to a scan tool still.... swap the #1 and #4 plugs and if you still get a P0304 reading you know the misfire is likely in the #4 cyl. wiring. (A faulty injector could cause a misfire but it's less likely a culprit than the wiring)
If you get P0301 code after you swap the plugs.. then you'll know it's a faulty plug.


sorry for the long winded advice.

2000 honda crv p1399 and p0301 check engine codes


Code P1399 is specific to Honda - it is an error code for "multiple variable misfires detected". P0301-P0304 are common OBDC codes for all cars, specifically "misfire in cylinder X".

You will get the P0301-P0304 codes on your OBDC reader when you plug it in (if actually errors), but will only find the P1399 if you select Honda as the manufacturer.

Just got these errors today on my CRV 2000. Now I have to figure out what is causing two of the cylinders to misfire.
