Check your O2 Sensor wire harness plug, they accumulate alot of oil inside of the connection, do to a drippy Distributor seal, Mine did.. and I was throwing all kinds of codes.. I cleaned it really good with Brake Clean, and allowed to dry well before reconnecting.

Yea, I cleaned the plug well before I replaced the o2 sensor. The car ran really well all day but its starting to act up again. I'm at a complete loss of what to do now..

I think that you should reconnect the vacuum line to the EGR valve and clean the EGR ports, because this is a common problem on Accords, especially with 300K miles.
Reset the ECU by removing the 7.5 amp backup/radio fuse in the engine bay fuse box for a minute. When the CEL turns back on, recheck the codes and post those codes on here. FYI, there is no code 2 listed in the shop manual, so that is why I want you to clear them and recheck. |
I replaced the o2 sensor yesterday morning, it ran a little rough last night but it did good all day today. No more jerking and hesitating when I accelerate. my check engine light is off and hasn't come on since I put the new o2 sensor in. Thanks everyone for the help, hopefully my problems are over.

Also reset ecu and rechecked codes, no codes. I'll post if anything changes.
