Bear with me on the noob shit, but I need to get this straighten out.
Fuel system is brand new, tank to the injectors. Literally everything. New ecm, TPS, IAC, new intake gaskets, cap, rotor, wires, motorcraft plugs, cleaned TB, no vacuum leaks, 100% stock down to the emissions. NO CODES. It sat for years and I replaced everything to get it running and up to spec.
It has a rough idle when I first start it. I can floor it and it clears out, but still has a hiccup or three till it gets up to temp. Once it's warm it generally runs fine. I've put about 600 miles on it hoping the new ecm may need to "learn" or something to that effect with no luck.
What am I missing or forgetting?
