1999 Cadillac Deville V8 Two Wheel Drive 118000 miles
It started with a P0307, so I changed all plugs and wires, code went off, then came back on a day later. Replaced the coil pack linked to that cylinder, then the code went to a P0305. Changed the other three coil packs, light went off for a few days. Then the light changed to a P0303 and has been on for a month. With A/c on idles rougher, but still idles a little rough without A/c on. Gas mileage has been very poor. Is this a MAF, or could it be an Oxygen Sensor?
