long story short, after my engine(4.6L V8) had a slight overheat (no coolant over-flow at all, just a warning light), it developed a slightly rough idle. i wouldnt mind except when its warming up in the morning it tends to stall out. the engine runs smooth as silk when under load and has pleanty of power, so i doubt i warped a head or anything. its got a new iac, new egr, new fuel filter, new spark plugs, and new ignition coils. the only things i can think could still be wrong are bad o2 sensors, or bad cylinderhead temp sensor, or maybe even a PCV valve. anyone else have any ideas? no codes of corse either.
