I have a 1992 Trooper SOHC 3.2 L with about 59 K original miles. I have noticed lately that my gas mileage has dropped to about 14.5 MPG around town where is used to be about 17 MPG. My highway mileage had dropped also.
I have changed plugs and wires, pcv valve is good. I have inspected all my vacuum hoses but have found nothing.
I was thinking that maybe the o2 sensor is going bad. I have no check engine light. Engine runs smooth just sucking more gas than usual.
Appreciate any thoughts from anyone.
