How do I fix this Pinging noise and lack of acceleration on my 1998 Ford Expedition?

As a vehicle ages, the timing gets off, and the Octane of fuel will compensate for an out of timing vehicle.
Bad gas is main culprit, also dirty/clogged fuel filter, or clogged carberetor or injectors!
Use a "GOOD" fuel system cleaner for the next 3 tankfuls, and use a higher octane fuel at the same time!!! This is important. After 3 tankfuls and 3 additions of a Fuel System Cleaner, go back to a lower octane fuel. Drive up a hill and see if the problem is gone. If not, then either take it to a mechanic and check timing, hopefully you replaced the fuel filter by then.

No acceleration when put in drive but idles smoothly in park. Why?

You didn't state the YEAR, MAKE, or MODEL of your car, so I have to answer generally:
  1. Fuel delivery problem (clogged fuel filter, defective fuel pressure regulator);
  2. Bad Throttle Position Sensor (if the vehicle is fuel-injected);
  3. Clogged metering rod (if the vehicle is carbureted);
  4. Vacuum leak;
  5. Clogged air filter or air intake obstruction;
  6. Contaminated fuel or water/moisture mixed in the fuel;
  7. Bad or misadjusted throttle linkage

Check owners manual or manually check to see if there is another fuel filter. Sometimes vehicles have more than one fuel filters which are overlooked until they have problems with them. Most have a filter right along the frame.

Engine performance problem causes are many. Try this first.
1. Disconnect the battery cables (both of them)
2. Touch/connect the postive and negative battery cables together for 30 seconds.
3. Reconnect the cables to the battery.
4. Drive vehicle to see if this solved the problem. Let me know what happens.
