In park and at stop, I feel a rough idle, or similar to how a “loping cam” feels

Looking for a local shop with Nissan Titan knowledge or expertise on tracking down similar issues, haven't found that guy, yet!
I keep the truck in good condition and want to pass it down to my son soon but want to fix this first.
What makes this problem better or worse?
Worse when cold
How long has your 2004 Nissan TITAN had this problem?
RepairPal Certified shops can diagnose and repair your 2004 Nissan TITAN. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Hi. No idea. Too many parts replaced indiscriminately. No guessing is possible. We can offer advice to get you on the right track, but when you've replaced all that stuff without any guidance or knowledge any of it was needed -- it's created so many variables that there's no basis to go off of anymore.
Hands on testing by a trusted technician equipped with proper tools and manuals is needed.

Thanks Dave,
I updated my question after your response.
I left out far too much critical data, my rookie mistake! LOL
I'm looking for a local expert but have yet to find that place here in SW Florida and I'm willing to travel if needed to get the problem solved.
The local Nissan dealerships are struggling with inexperienced mechanics at the moment, so that option has yielded no help either.
The local shops on the repairpal.com links are in the same boat, they don't know enough about Nissan Titan engines or don't have the proper diagnostic equipment.
Again, thanks for the note!
