Stumbling 4.0 in wifes GC?

Hi I'm new to this forum and need some help with my wifes 97 Grand Cherokee. The motor stumbles badly at idle. MIL light is on and keeps throwing misfire codes. I've done a tune up and changed one weak injector (number 5). Still no better. Any ideas would help. I've never had this problem in my 93 Wrangler 4.0, so it's a new one to me. Please help.

Change 02 Sensor, run some Chevron Techron Fuel Injector Cleaner through, take out plugs and check condition of plugs and wires, re-gap plugs if needed, change fuel filter. Thats a start.

Stumbling GC 4.0

Thanks for the tip. I'll give it a try. I'm at a loss. The misfire codes are moving around to different cylinders.
