I have a 1993 Jeep Grand Cherokee V6 4.0, that idles rough. When i put it in gear the rough idle is felt even more. I recently had to put a new CPS in when it stopped running. Now it runs, but not smooth. People told me that a cps either works, or doesn't. I also did plugs, rotor, cap, wires, and fuel filter. There is no check engine light on either. I am out of ideas. Any advice would be greatly appreciated.
Thank You
