Help please

hi guys I am in need of some help.... I have a 2002 ultra that I am having issues with and don't know what else to do at this point. It had an intake leak which I changed out the gaskets and fixed. It was stalling/missing at idle and low rpm I did some research on the forums and the consensus was that it was probably the idle air control which I switched out and stopped the stalling/missing problem while idling but it still wanted to stall/ miss at low rpm so I did more research on the forum and narrowed it down to possibly the TPS which I changed out today....did not fix the issue and I have no idea what direction to go from here. Any questions input or suggestions will be greatly appreciated
thanks in advance

Does it do it hot or cold or both? Does it do it with a full tank of fuel or when it is low? CKP possibly?

Diagnosis on the forum is difficult. I would get a service manual for your year / model of bike. This should prove most helpful. Vacuum leaks, fuel filter, front plug wire rubbing on the bottom of the fuel tank. Vacuum cap off on the top of the manifold. etc.

Both on the hot and cold though it seems to be worse when hot. It also does it with all levels of fuel forgive my ignorance ckp?

I have the service manual I just don't know where to go from here? Might be time to take it to the dealer again. I just had it in for the 15000 mile service and they told me about the intake leak but saw no other issues

If your bike is EFI check fuel hose inside the tank for cracks or pinholes. That would cause missing and/or backfiring. Change filter while there.

+1, exactly what I was going to recommend. Friend had a small leak on fuel line inside tank that was causing the same problems you're describing. He replaced all lines, bike ran like new.
