RE: Bucking while driving
 

The problem hasn't come back.

I haven't sent off the injectors yet.

I still am leaning towards the O2 sensor, but that is based on other posts I read in several forums. My check engine light was never on and no codes were stored. I would make sure that your ECU doesn't have any codes stored.

How has your car been? Ever test the injectors?

I didn't send off the fuel injectors. I packed them in a box this morning and was going to send them off to get cleaned this week. After I replaced the O2 sensor, that bucking problem did not show up until last week. Recently, my car has been having problems that might be fuel related.

I have gotten a code 43 four times now since Christmas (either O2 sensor or fuel supply system). I had one pop up last night and it returned this morning while driving, so I cleaned the O2 sensor plug and put some dielectric greas in there. I wish the problem was there all of the time, so I could figure this one out.

I think that I might just order the honda fuel pressure gauge and test the fuel pressure at the rail while driving. This is really frustrating right now.
