I have a 2000 Ranger 3.0L V6 with about 105k miles on it. Recently, my truck began to idle very poorly when starting cold. I have quite a few symptoms to help diagnose this, so please bear with me. The idle on cold starts is rough, gurgling, it almost stalls (and sometimes does) and the exhaust is unbearable until the engine smooths out (not sure if the smell is really rich or lean, but it smells as if you've got your nose next to the tailpipe while it's idling rough). After you run it for a few minutes - flawless idle and the engine appears to be working perfectly fine. Sometimes, the "transition" happens while at idle. It's rough - rough - rough and then all of a sudden it's smooth without any revving. The time it takes for it to smooth out varies wildly (this morning I made it all the way to work, about a 10 minute drive, with it idling like crap). There is no noticeable power loss at speed.
I've cleaned the mass air flow sensor, idle air control valve, replaced the DPFE sensor, plugs, wires, fuel filter, air filter, and just about everything else I can think of.
One possible culprit, although it seems unlikely to me, is the ORIGINAL, Ford battery that STILL starts my truck. For whatever reason, miracle of miracles, in the nearly 11 years I've had my truck, I have never replaced my battery - but it starts just fine and I've never had an issue (spent 3 hours with the radio blaring the other day and it started right up without issue).
Any ideas?
