96 Explorer help

[djjhlgh]

Hello all!! I've used this site for many repairs I've done to my explorer! Very helpful I must say!! I have a 96 Ford Explorer Sport 2WD 4.0 V6 5 Speed I love my truck and now need some serious help with it!!! In the last three weeks or so it has been bogging down sometimes while driving, I've been to my local Autozone to have the codes read and have replaced tga MAF sensor, TPS, EGR pressure sensor, FPR, fuel filter, fuel pump, spark plugs, igniton coil, IAC valve, and air filter and in January of this year the plug wires and now she seems to be either misfiring or not getting enough fuel! Also have changed the tranny fluid, slave cylinder, and differential fluid (not that that has anything to do with the running/starting problem just noting all the work I've put into my baby lol) can anyone help or suggest anything to help? As of now when I start her up she runs really rough unless I keep the RPMS at 1500 or more, but even doing that I can't drive because when I put her in gear it feels like the engine is going to fall out is how rough she runs? Help!!!

Bad vacuum leak?

Bad cam position sensor or syncronizer?

Clogged catalytic maybe?

Had a mechanic buddy come over to look at it and seems like the timing has jumped, going to replace and fix and hopefully nothing else goes wrong, ice dropped a lot of money in it into the last 3 weeks!! Thanks for the suggestions I did check the vacuums and catalytic converter they're good!
