what up everyone I'm a new member here but this site has hooked me up with a lot of help on my truck. anyways I have a 99 ranger 4.0 4x4 104,000m. when I crank over the engine it wants to die right away so I have to give her a little gas. also when i'm idling or coasting the rpms will drop down to 500. i just replaced spark plugs and wires, fuel and air filters. i'm thinking it might be an oxygen sensor but any ideas are appreciated.
