My CEL comes on, on my '94 XL, when the engine is under load. Meaning, at highway speed, or when pulling a hill. I purchased a EEC-IV code reader ('cause Auto Zone won't test vehicles that old) and came up with the following codes;
543 O,C Fuel pump secondary circuit fault
186 C Fault in injector pulse width circuit / high
Now...my stupid question is...what's broken? What is it, exactly, that these codes are telling me to fix?
