Town and Country Starts and Dies when Moving

[MinnieRolltide]

2002 T&C, starts and idles fine. When we put in gear (drive or reverse) it dies. Then we can restart and it drives fine the rest of the day. This only happens when it has been sitting a long time, such as over night. However, I've let it sit until mid-day and it does it so it doesn't appear to be Temp or humidity related as it issue is repeatable at any time of the day as long as the vehicle has been sitting 12 hours or so. The remainder of the day it drives without issue and we can restart 8-10 times during the day without issue, then the next day when we restart it, no matter how long it idles it cuts out when you first start to move and apply the gas. When you restart, it, it often doesn't happen again and I've never had to restart more than twice. Again, it runs fine other than this issue.


I've replaced the fuel filter and I put a pressure gauge on the fuel rail. The pressure is within specs. I also watched the gauge as my wife backed the vehicle up and it died, but the fuel pressure didn't drop out.



It is now showing a O2 Sensor code per Advance, but in reading other post, those can be misleading, so I wanted input before I just start throwing money at the problem

My '02 Dodge Caravan (3.2 eng) did this too.
I pulled the throttle body and cleaned the idle air piston and chamber to solve the issue.
It is the square aluminum housing between the air intake tube and the manifold. Only has 4 bolts. and 2 electric plugs, so it is an easy job. Pull the idle air cylinder off the body with 2 bolts and pull the piston out to clean.
Cleaned all the parts with a can of brake parts cleaner.
