1999 Ranger problems PLEASE HELP!!!
I am new to the forum, and have been having some problems with my 1999 Ranger xlt 4cyl. My issue started about a month ago, When ever my fuel level got below half a tank my truck would not idle and would run horrible. while driving in 3rd or 4th gear I would put the pedal to the floor and the truck would almost feel like it shut off, then all the sudden jolt and take off again.... I have noticed that it does this mostly when my tank is half gone. I tried plugs,wires,coils... nothing. for some reason a OBD II scanner will not connect to my truck, it says "unable to connect to vehicle". I am at a loss guys gas mileage has dropped, stalling all the time is embarrassing... Please any help is greatly appreciated. Oh, and i did unplug my mass air with little to no chage while driving.
Thanks in advance,
