Mass Airflow Sensor on 2002 Ford Escape
Had the same problem, took the escape to a mech and he replaced the rear catalytic converter. The engine regained all power and has been running fine for the past 9 months. No issues after the replacement. Mech said it was a good thing it was not the catalytic converter(s) off the exhaust manifold or it would have been expensive.

Have you checked the trouble codes? This can be caused by several thing, so you should start with codes, check fuel pressure, and check the exhaust back pressure before replacing parts.
Yes, also check your coils, and you catalytic converters.
I am going through the same thing, all I can say is it looks like the EMG Valve and/or the EGR Pressure Sensor. My ran like **** for 4 months, then the Valve blew out, replaced it and it blew out again within 24 hours. Now I am told it is the EGR Pressure Sensor. Check it out!
