Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.

the battery is going weak. check voltage at battery when engine is off, should be at least 13 volts if alternator is ok. when running if alternator is ok, then it should read at battery post at least 14 to 14.5

Good Evening, you might want to check those injectors, I can not remember for certain but that setup was sequential and when one or two have a problem it would take out the rest. Ohm out the injectors and see what you have there.

Put an ODB-II meter on it and look at fuel trims, air flow, and O2 sensors. Also follow any codes it might have. I would guess maybe intake plenum gasket as these crack often on the 4.0L.
