Hello my friend has a 2002 grand cherokee overland with the high output 4.7 and since he bought it, ( a couple months ago) it stalls when he's letting off the gas to come to a stop. Changed map sensor, evap vent control valve, tps and plugs and it still stalls on him. Can't figure it out and neither can the shop he took it to when I couldn't figure it out. No light on, went off when I changed the evap piece. Also fuel pump, screens and filter were replaced.

Remove and clean throttle body. Also remove and clean/replace IAC. 2 nearly free things you can try.
