Question about Cadillac DeVille
Ther are a few things that can cause a lean condition. A weak fuel pump or pressure regulator, clogged air filter or fuel filter. defective altitude sensors, vacuum leaks, defective 02 sensor. Only way to know for sure is thru diagnosing. The longer you wait to have it done the more damage you will do to the catalytic converter.
