Well, you have spent allot of money and the problem is still there. It can be many things. My guess would be vacuum leak. Replace all vacuum lines, (cheap fix and probably needed anyway due to the age of the vehicle) and see if that fixes it. If not, Stop throwing parts at the problem and take it to a professional and have it fixed. You would be money ahead if you had done that in the first place.
Check for fuel pump pressure; You may have a weak fuel pump. Sounds like a possible plugged catalitic converter?

That converter is on the recall list. check it out.
It is inside the torque converter.
No. The torque converter does not have a drain.
One per cylinder.
yes, yes you do
check fuel presure and mostly volume, restricted filter? Rick ASE L-1 Master TransMichigan.com
I'd vote for the injectors. Try a professional fuel injection cleaning. Occasionally run it up to 3500 rpm for 30 seconds in low gear to keep breaking up the carbon deposits.
It is in front of the catalytic converter.
if it is an automatic could be spark plugs or spark plug wiring...if a manual check the fuel pump
catalytic converter circuit
Yes, it is a fedral law that all vehicles built with a catalytic converter have one in working condition.
One per cylinder, 4, 6, or 8
They are under the coils, next to the fuel injectors.
It has eight, one per cylinder.
Federal Emissions specification Cherokees have 1 downstream Cat Converter. California specifications Cherokee have 2 pre-cats and 1 downstream Cat Converter.
prolonged use could clog up your catalytic converter with unburned fuel, but if the engine will stay running with the vacuum leak you shouldbe able to limp it home, be sure to get it fixed soon, the poor runing, the shaking, stalling, and sputtering will eventually lead to bigger issues.
You have to get that from the dealership. Law states you dont have to pay to have the converter replaced
