Serpentine belt tensioner is jumping and acting weird
The fact that you finagled your belt length tells me that's where the problem is, and the symptoms indicate a belt that is too long. As the slack builds in the belt, the tensioner moves to take it up, and then when the tension momentarily increases, the tensioner jumps to compensate. If the belt is the right length, it'll pretty much run with a fixed tensioner, and the spring action is only there to compensate for wear, not 'adjust' the tension.
The AC-delete pulley that I used (before I bought the proper AC-delete alternator bracket), uses the same length belt as stock. It doesn't matter if you have Jeep, Ram, Van, whatever....if the PS bracket is from that system, the AC-delete pulley puts the extra roller in the same spot so you DON"T have to go hunting belts.
If you use the proper Mopar non-AC bracket (which is a ***** to find, even in Alaskan salvage yards), the belt length is not the same even though the overall routing isn't much different. And don't even think about some of the half-assed 'make it work' re-routing solutions you see online. There's the right way, and then there's that way.
The stock belt doesn't go on easy. To me, they usually seem 'too tight' when I put them on.
My guess: the OE-length belt will be shorter than what you have on there now, and will solve your problem.
FYI the pulley I used initially looks like this, and had three mounting bolts.
Edit: And then I re-read OP's post and saw that he deleted the PS pump. Same advice; get a tighter belt.
