My 07 honda pilot has a jerk when at a stop and hesitates when taking off. I tested it and came up p404 I checked and switch cylinders and the same code. I checked the fuel injectors the egr and egr ports. Any ideas where I should look next

Read about it here:

Not sure what you "checked with regard to the EGR but these are the causes…

Usually this code points to either carbon buildup or a bad EGR valve. However that doesn’t rule out the following:
Open or short in the 5 Volt reference circuit
Open or short in the ground circuit
Open or short in the PCM controlled voltage circuit Bad PCM (less likely)

Did you check any of the 3 likely open or shorts?
