ENGINE LIGHT-06 4X4

2006 Lincoln Navigator • V8 4WD Automatic • 82,000 miles

I have a 2006 lincoln navigator 4X4 ultimate. The engine light has come on several times. My mechanic has changed both catalytic converters, new plugs, plug wires. Any advise on what else needs attention?

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
