If there is no check engine light on I would go the local auto parts
store and check out the TP sensore first and then the Mass air flow...

Try changing the throttle body position sensor, or the ideling screw. , Service the fuel injection system (injectors and filter) have the gas tank washed as there could be rust paricles in it. and if that fails you will need to have an engine job done. Chances are the pistons are worn out or the rings are bad.
Other possible causes are the torque converter or the transmission itself, However if it coccurs with the ac, it means that it happens when extra stress is on the engine. This is caused by eighter the fuel system or the engine itself.

the idle air control valve is responsible for engine idle.
this is a common failure on ford's. but I don't think yours is bad because it does idle high befor it dies.
you stated you had codes p0171 and p0174 these are lean codes for bank one and two, you said you found a vacuum leak and repaired it, the vacuum leak was mostly likely the cause of the lean codes, however the pcm has calibrated the fueling stategy for this lean mixture, what you need to do is erase the KAM "keep alive memory" this is done by unhooking the negative battery cable for 60 seconds, this is the only way to erase the KAM the $6000.00 machine I use wont even do it.
once the KAM is clean the computer will go into a relearn state and all operating values will be adjusted for the vehicles current condition, during this relearn session the vehicle may have some driveability issues (low or high idle, stalling, poor fuel economy) the relearn should complete within 10 minutes of idling and then 10 minutes of driving.
good luck and keep me updated

When you say it's destroying the air filter---do you mean it's all sooted up ?? I am assuming that what you mean.
Try disconnecting the vacuum line at the egr valve and see if that helps.
But it sounds more like a plugged up exhaust system.Try disconnecting or looosing the flange before the cataylic convertor and then see how it runs.
