I am driving a honda fit 7speed auto transmission. I started noticing some jerky/stutter movement while driving at low speed. It happens often when i drive uphill. It is not a misfire its something else. There is no check engine light. I changed my spark plugs, coil pack, transmission oil, fuel filter, cleaned my EGR and carburetor but the problem didnt go away.. last year september i replaced the transmission gearbox and the problem went away. Its hasn't even been a year now but the problem started again and i don't know whats causing it

 

check the fuel pump plug, very easy to access

 

Where can i find this fuel pump plug?
