94 Cherokee more info û

Thanks for the info, the bat voltage does settles down after 30 min or so. This is a rebuilt engine and all the ground straps are clean and tight.

Sometimes it will idle just fine, and just cut off. When it is idling fine and I barely crack open the throttle it spits and sputters? Could that be the TPS? What is the other sensor next to the TPS? Sometimes it will smooth out and I can ease it around the block a few times, but if I get on it, it bogs out and goes back to spiting and sputtering.
Thanks again
