I HAVE A 99 JEEP WITH 147,000 MILES, IT RECENTLY STARTED RUNNING ROUGH AND ACTING LIKE IT WANTS TO DIE. I JUST PUT A NEW RADIATOR ON IT AND THAT WHEN IT STARTED RUNNING ROUGH. THERE IS NO CHECK ENGINE LIGHT ON. OTHER THAT A TUNE UP WHAT COULD BE A FACTOR? THANKS FOR THE HELP

When was the last tune up? Go with the basics first, engines don't run without a solid foundation. Plugs wires and filters. Do that and let us know! If you are gonna throw parts at it, lets at least have it run good when done!

Make sure you plugged the coolant temperature sensor back in. Did you change the thermostat.
People have been known to put them in backwards.
Re-inspect everthing you touched and everything else nearby where you were working.A loose connection at a sensor, vacuumn line, or even a loose ground wire can cause a rough running condition.
