If that is p0661--4, I found the codes, but, I can't find info that says they apply to your vehicle? MOD doesn't list those codes for your vehicle. They are codes for intake manifold control valve circuit. That valve usually applies to a spider fuel system. I haven't worked on your particular year--make--model.
