Hello all, this is my first post on here. My dad owns a 2000 Ford Ranger pickup with a 4.0 liter engine and lately it's been starting fine but won't stay idleing. If you let off the gas it'll die. But after a short while of this charade you'll here a click and it'll idle just fine. Is there some sort of relay in there that's not working properly, or what can I look for that would be causing this problem?
Thanks in advance!
