Customer Question

the Issue is the P1399 code in a 2000 Honda accord V6. It also spudders and dies sometimes if you do not pump the gas
JA: Thanks. Can you give me any more details about your issue?
Customer: That sums it up. The code reader says blocked EGR, and valve clearance. But ive read on the internet anything from PCM, Fuel presuure regulator and fuel pump

Welcome to Just-Answer. My name is ***** ***** online handle is Honda-Man. I have over 31 years experience repairing Honda and Acura vehicles. I would be happy to assist you with your Honda or Acura question!

Your problem sounds like a bad fuel pressure regulator. remove the vacuum hose when it's hot or prone to acting up. Any fuel or fuel smell in the vacuum hose means the fuel pressure regulator is leaking. The EGR valve can also cause issues if it's not closing at an idle or hanging open. When it's acting up check the EGR valve lift voltage with your scan tool. It should be under 1.25 volts at an idle. if it's above 1.25 volts replace the EGR valve. Last thing can be caused by tight valves. If all else looks good try adjusting the valves.
