i have a 99 696 3.2 liter that is getting horrible gas milage, im talking like 5-10 miles to the gallon. it feels like the engine is lagging almost as if my brake is on. the check engine light went on and i ended up replacing all the O2 sensors to no avail. anyone ever experience this problem. i dont know what to do, im spending $100 in gas a week to commute a short distance each day. Help, help, help.
