I've got no diagrams on this car but I'd check mass air flow sensor if you have one. Often they can be cleaned off and work well afterwards, or replace it.

    I would have someone put a code reader on there and see what you get... common for computer to "cover up" problem in one area by overcompensating in a different direction. As I said I have no info on your car but generally that's procedure on just about anything. AND it eliminates a bunch of guessing.Also being weather and bump related, I'd just unplug and plug back in everything I could find, just to insure that connections are clean and secure/

Stalls out when gas is let off


You don't say what size engine you have, so diagnostic analysis is a bit difficult. Please supply engine size and answer these questions.

1. After it stalls, do you sometimes smell fuel?
2. Does it restart easily after a stall, or do you have to hold the gas pedal to the floor to restart it?
3. Can you keep it running by working the gas pedal?
4. Has you fuel consumption increased since this began?

I ask these questions because on most engines there is a coolant temperature sensor that the ECM used to control the amount of fuel to the injectors based upon the engine coolant temperature. When the engine is cold it supplied more fuel than when warm. If the sensor malfunctions it tells the ECM that the coolant is -40F
and that causes massive fuel to be supplied. This may not affect a cold start once the engine needs the fuel, but it will flood and stall out the motor when warm. If you can keep the engine running by pressing the gas pedal, you are allowing the motor to rev up and use the extra fuel, but you will find you gas mileage reduces by as much as half.

you may have a dirty fuel filter or the throttle plate may need cleaning.the throttle plate is the valve that moves in the intake when you move the gas pedal.if they get too dirty they cause a restriction in the intake and cause the car to stall.it also could be a tps sensor problem but this should put the check engine light on but not always.the breaking up of the motor when you rev it to 4000 rpm`s is the rev limiter in the computer that shuts down the firing of the plugs and injecotrs so you don`t cause damage to the motor when there is no load on it.

Mitsubishi Triton V6 lacks power on acceleration


full power is only achieved when the engine is fully warm(operating temp).so if you accelerate more than, say, a third of the gas pedal,the car will feel sluggish.
this is more apparent when first starting the car in the morning in winter.almost like the car is going to stall.
most wear in the engine is leaving it to idle when cold you should always drive the car straight away from cold.then when hot turn on the a/c if required....

One of your intake manifold gaskets went bad and it is sucking in air where it should'nt be. This problem is very common on this motor. I'm 100% sure that is what it is. But no ofense if you can't figure out how to get your radiator cap off , then this job is probably a little much for you.

Engine over-run between gears


This is a very common problem for ford. I have the same thing every day. It is the computer not reading the temp. When it does that just tap the gas pedal.
