Question about 2000 Jeep Cherokee
The dancing needle is caused by a bad contact at the battery clamps - the battery is left out and the voltage at the alternator varies wildly.
That voltage variation is definitely capable of causing all the other problems so clean the clamps thoroughly with wire wool and get a new battery.
If even this doesn't fix it then the only thing left is a bad contact in the wiring to and from the ECM. So check them all, including the wires to the sensors.

Are you thinkng about the coil packs? were covered under the extended warranty to 120,000
miles. If your DTC is throwing those codes the dealer should have
replaced them free of cost. Had the same problem and they replaced mine
Test it and tell us news.
