I have a 99 Civic GX and we had three error codes -
P0300 Random Misfire in 1-4 cylinder
P0193 Fuel Rail Pressure Circuit
P0420 Catalyst Efficiency Low on Bank One
The local Honda dealer says we need to replace all four fuel injectors to fix the first item, along with new plugs since the injectors have cause carbon build up.... total $2,270
The second item the found a small leak at the pressure regulator and recommend replacement .... total $2,020
The third item requires catalytic converter replacement... with new oxygen sensors.... total $1,180
without new sensors total $780
For 99 Civic that amount is close to the total value of the vehicle.
Has anyone had seen these codes? Does anyone have a workaround or a way to clean the existing injectors? If so, how is it done?
Thanks in advance for your help.
