Misses when hot
I have a 94 F150, 5.0L, automatic 55,000 miles. Misses when outside temp is hot. Truck runs fine early in the morning or late at night. Checked codes, it set a code 173 (O2 sensor), changed sensor, cap, rotor, wires, plugs. Truck ran great the next morning, outside temp was 65 degrees. That afternoon temp was 90 degrees, drove truck 2.5 miles started skipping, lost power, and check engine light came on. Changed coil same problem. Any ideas?

Disconnect the negative cable for a minute to clear all codes. Then re-connect and drive for a few miles and record any new codes. Don't buy any more parts until you can pin down the problem with error codes.
