Question about 2002 Cadillac Deville
I have a feeling the problem is not the sensors, they are reading lean indicates that air is getting into the engine around monitored system, basically a vacuum leak, which causes surging, also get a real time engine monitor not just a code scanner, some even have snapshot capabilities that will freeze the readings when something abnormal happens, just don't go replacing parts without knowing why
