I have a 2008 Honda Accord 2.4 L that was having an issue going into limp mode, scanner showed Crank Shaft Position sensor, replaced that and relearned it, replaced all four injectors, replaced all four spark plugs as well as all four coils, we were still getting a misfire code so replaced the oxygen sensors upper and lower. That helped it run smoother and it runs good after clearing the code and getting up to speed it never throws a code while driving and rpms are elevated, however if you pull up to a stop sign it will misfire and throw a code. I can pull over clear the code and drive home with no codes until I pull into the drive and sometimes after a few minutes it will show another misfire. Any suggestions what else might need to be replaced?

 

please put down the parts cannon and back away slowly...

after installing what- $300 in parts it may be time to cut your losses and get a real diagnosis from a professional. That won't do if you're hard-headed like me, so as an alternative get one of these and follow the diagnostic steps closely.

Also you'll need to share the specific code #'s to get any useful feedback from the other users.
