The MLPS and original DPFE sensor (aluminum box) are the only sensors likely to fail. Oxygen sensors have a lifespan of around 100k miles, so they "wear" out. Otherwise, everything that fails is just chance, age, and/or neglect.
..... on my 95, the EGR tube got plugged at the orifice between two little DPFE tubes (signal and reference I believe they are called).
I've also had to replace:
ECM - twice
Charcoal canister flow valve (or flow sensor - don't remember which one)
Plugs and Plug Wires
Thermostat, ECT Sensor, Water Pump, Radiator, Electric Fan, Accessory Belt, Relay Module, and missing Air Dam (when I was having an overheating problem in the hot Florida summers)
Oil filter adapter gasket (infamous on ALL 4.6L engines)
Valve guide seals (infamous on pre-F5 4.6L heads)
PCV valve & PCV valve grommet
misc. vacuum lines
Trigger wheel and Crank Position Sensor
Odometer gear in dash (another infamous thing in these cars)
Sway bar links
Control arm bushings
Upgraded a bunch of stuff that wasn't necessarily NEEDED
I'm sure there were other things I'm just not remembering at this moment.
