I've got an 03 Ranger, 2.3, automatic, 2wd that I'm absolutely sick of..
It has a "knock" that has developed under the hood, it only happens when the engine gets to operating temp at idle and I turn the headlights and/or put the transmission in gear with my foot on the brake. Otherwise it goes away...
When the "knock" starts, the Speedo needle will slowly fluctuate between 0 and 10 mph, sometimes going as high as 20 mph and back down to 0 all while the vehicle is not moving, doesn't matter if it's in gear or park.
I can't for the life of me figure our what is causing it nor can I isolate where it is coming from, even with a mechanics stethoscope. It does not sound like a rod knock and sounds as if it is coming more from the topside some freaking where. It sounds like if you were to slightly tap your knuckles on a desk. I've tried an oil change with a thicker viscosity oil and Motorcraft filter but it didn't change anything. Alternator tests fine, only code I have is an evap code.
I can try to explain it more clearly if my post is confusing.
