Jeep Stalling

Hi, I have a 2001 Wrangler, 4.0 automatic. 2 weeks ago it stalled on the wife. After a while it started and drove it home. No check engine light or codes. I changed the spark plugs and cleaned TB. Helped overall engine performance and thought (hoped) problem solved. Ran fine for a few days until this morning. Was just driving along at about 35 and engine just quit. All lights and radio were still working. Waited about 5-10 minutes and then it finally started. Don't know if it matters but it was in neutral when it started. Any ideas on what to try next? Why would there not be any codes? Thanks.

Iac or crankshaft position sensor will cause it to shut off

Check your iac first as cps is like $89.99

Check the fuel flow, the little pressurization nipple under the hood (looks similar to the AC recharge nipple) inside is a similar mechanism like a valve stem of a tire, press the little center node with a tiny screw driver or pin, fuel should squirt out. If your electrical devices still stay on I doubt it's an electrical issue. I wouldn't think it's your evap canister, as that would probably throw a code, and same goes for your fuel sending unit in the tank...start with the simplest thing and work up from there I guess.

Mine did the same thing. It was the cat. The cat was broken inside and it would backup exhaust into my engine and choke it. Maybe your O2 sensor isn't picking up the problem yet. It took awhile for mine to register it. Or maybe your O2 sensor is bad, and not picking up the cat problem. I would take it to a good muffler shop and have them to check the cat. The car won't be running when they lift it, so its hard to tell if the cat is bad unless they shake it or tap it lightly. If you hear broken glass noise inside the cat, then that is the problem.
After 12 years of road jiggling, and maybe some moderate off road use, the cat might be broken. This is a good place to start. It will probably solve the problem if your cat is broken.

Same Problem

I am having that same issue with my 98 Wrangler stalling, will start either as I am slowing down or after a few minutes. No rhyme or reason.

Thanks for the info
