Issues with 98 jeep Cherokee stalling or shUtting off

This happened to me I've been dealing with my 98 jeep Cherokee for the last six months and replaced everything on it map sensor as well as replacing all sensors on truck ignition coil, fuel pump exshust radiater, spark plugs PCM twice cavillitic converter , muffler, fixed wiring, did bolt twist new battery , everything ! Then got my transmission fluid flushed and replaced and since I did that it hasn't had one problem ! Just wanted to let everyone know that could possibly be the problem causing the tramission throttle not getting enough air if its clog or old fluid
