Hello, my wife's 02 Town and Country 3.3 Flex, with 191K on it now, was intermitently stalling when sitting at a stop light / sign. The RPM's just drop off and stalls. Its been bothering us for the last 4K miles or so, but is now happening more often. I had the melted fuel injector harness last summer and repaired it. Had the tranny repaired @ 188K and found the EGR control unplugged when I got it back. Replugging that in helped a little. There are no codes and a friend has a hand held analyzer and all sensors appear to be in normal ranges. I saw a few threads here and tried some things. I pulled the throttle body off and cleaned it and the IAC valve. I then replaced the IAC on the suggestion of a thread. Pulled the EGR and cleaned that. The plugs and wires were changed last year. The fuel filter has not been changed.

Everything has helped a little at least short term, but I can't totally get rid of the problem.
Any one know of anything else to look at ?? Thanks in advance
