CEL Combo what does it all mean?
I've got an 04 6 speed. It starts and runs great. No hesitation or bogging down yet I see P0301 Rotor 1 misfire detected. I tried swapping the order of the coils to see if the problem followed to Rotor 2 but no dice. There is one thing that seems out of place and thats a defauler plug extension thing. This problem has been constant before and after new coils, wires and plugs.
The P0661 is? Is this a dirty SSV valve error or are we talking about the three solenoids near the firewall? Could this be causing the other CEL messages? I'm seeing that U1900 is either a bad can bus or injector malfunction. Are maybe the injectors dirty and are causing some misfires??? Any help greatly appreciated. |
Defouler plug extension? There should be no such thing, unless I'm not understanding what you mean.
P0661 is one of the relays. U1900 i have no idea. Clear it, see if it returns. |
