1997 Jeep Grand Cherokee Limited 4.0L v6 Needs Help?

Either the before or after cat O2 sensors could also be causing the problem. also both could be a problem. Check engine codes if you have an engine light on. Those sensors going bad will give the PCM bad readings and will cause the fuel system to starve the engine for fuel and make it sputter and/or cut out. Ive had this happen and after replacement it came back to life. Good luck!
