Hi everyone,
Been having some issues with my 2001 Honda Accord EX 2.3L 4 cylinder. About a month a half ago I ended up getting a code of P0401 Insufficient EGR Flow. From my understanding, these cars tend to build up a lot of carbon through the EGR port between the intake and the EGR Valve.
Anyways, for that month and a half, I ignored it. Finally one week I decided I was going to fix the code on the weekend, but by the middle of the week my car started misfiring.
I then had the following codes:
P0300 Random/Multiple Cylinder Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0304 Cylinder 4 Misfire Detected
P0401 Insufficient EGR Flow
I've read that due to insufficient EGR Flow, it could make the engine misfire. Decided to take my chances on cleaning the EGR port between the intake and EGR Valve and also cleaning the valve itself.
This was performed this past weekend and the car is still misfiring. I cleared the codes, but then I end up getting the following codes:
P0303 Cylinder 3 Misfire Detected
P1399 Valve clearance out of range (Not sure what this means exactly)
Should I take my chances and buy a new EGR Valve? or am I missing something here? Originally I thought I would have to clear the EGR ports in the EGR Chamber BUT i saw that these 2001 honda accords don't have that chamber. I've cleared what I could.
Ideas? Thanks to anyone that replies in advance
