So, my 1998 Ford Explorer (now with 210,000 miles) has been running rough in this desert heat (110F+).

While doing some research, I came across the following helpful resources:

How Does a 1998 Ford Explorer Mass Air Flow Sensor Work?

Symptoms of a Bad MAF
Mass air flow sensors on the Ford are not repairable but can be cleaned if done properly. It is common on a Ford Explorer for the mass air flow to get dirty which will give low numbers and cause the computer to lean out the mixture (less fuel, more air). When this happens, the check engine light will come on the dash, the idle will get rough and there will be a loss of power due to the lean condition. A pinging caused by detonation in the engine may also be heard.
