1994 Ford Explorer problems

I have just bought a 1994 Ford Explorer with a 4.0 engine. When it starts it will idle very bad until it warms. I replaced the MASS sensor and same thing still happens.I can unplug the MASS sensor and it will idle very bad but it will stop running when I plug the MASS sensor back in.

Problem number 2: It will not shift properly. I use it in the OD selection and it takes it almost forever to change into the higher gear. Dirty filter?

Try replaceing the Idle position Sensor. It's located on the left side of the motor bolted onto the air intake manifold.

I'm also having a problem with my Ford Explorer 1994. My Jeep stopped moving in the middle of driving it. I can turn it on and the engine sounds fine but once I put it in drive or reverse I can feel the jeep shift into gear but it will not accelerate at all no matter how much I press on the gas. One of the hose from the intake came a loose and I have no idea where it goes.
