Do bad O2 sensors have the potential to cause really bad mileage? If they are bad, or are not performing appropriately, will it cause a fault code? Or do I actually have to get a multimeter in there to see if they are putting out correctly?
The Truck: '01, 95k, 4.0, AW4, 242, Mobil 1 and synthetics in diffs, 3 inch lift, 30's, 3.55's, and a ton O steel protection, resulting in 10-12 mpg round town. I do have a heavy right foot too. But is does seem to be signficantly less even when not in a hurry! If I concentrate real hard, I can get up to 13-14 round town. But I gotta REALLY concentrate.:sunshine:
That '01 4.0 actually has 4 O2 sensors hanging on the exhaust. At 95k on it, it's likely to need them, but I'd rather not go to that expense if they are working propperly.
Any suggestions?:viking:
