I have a 2001 jeep Cherokee, when you pull up to a stop light it will randomly shut off. I’ve replaced cam sensor, Crank-sensor, shaft that drives the Cam position sensor, and put a new pcm on it. Any suggestions to why it’s still shutting off?

Yes it is likely that your idle air controller needs to be cleaned, or replaced. It is located on the throttle body. It can get dirty or carboned up. Cleaning is cheap, try that first

Well that's a drag.

Is it an absolute sudden shut-down or a sputter then shut down? No problems during normal driving?

Check fuel pressure and clean/replace all the fuel injector screens.

I think I'd check CPS/CKS sync too.

It’s almost like you cut the key off. It runs great other than the shutting off fact. Like I said I’ve cleaned the throttle body, new iac, and tps, new cps, and crank sensor, new pcm,new cranksensor drive new asd relay, I don’t know where to go with it at this point
