I can't get the clip off the electrical harness undone! Arggghhh. I got the little gray clip and fuel line off with no sweat, I got the pressure line off no sweat, but I cannot get the clip for the wires undone.
I've used PB blaster to loosen electrical connectors before, any liquid might help losen the crud. Just make sure it's dry before powering it back up. Vibration also helps but you have to be careful not to break the connector.
That code means the computer has asked the fuel injectors for the maximum amount of gas and the engine is still running lean per data from the o2 sensor. Can be bad fuel pump or o-ring in the fuel pump, or bad o2 sensor, or really anything that can make the engine run lean.
