Chrysler Repair: 1997 Chrysler Sebring LXI, chrysler sebring lxi, 1997 chrysler sebring lxi

Question
Roland.  
I,m frustrated and stationed overseas and could use some good advice.  Over the past year I've had problems with my 1997 Chrysler Sebring LXI.
I have the VIN N, V6 EFI engine.  
I changed the electronic distributor (small rotor)and other parts you see below and it ran great for about 4 months. It is now starting to act up after I thought it was repaired. I,m having the same symtoms as before.  When it reaches operating temperature (normally 15 minutes), it begins to miss at all speeds, and stall, if I'm at creeping speed.  Take note of all parts I've changed in the past.
PCV Valve  
MAP sensor
TPS
EGR and Sensor
Spark Plugs and Wires
Distributor Cap and Rotor
Electronic Small Rotor Distibutor
I order a new IAT sensor twice, but they keep sending the wrong one.  The only thing I have not changed is the IAT and Catyictic converter.  My DTC codes give me a code 12 (battery disconnect) when it stalls, but all systems pass. Have any advice you can pass along to me.

Answer
Hi Ricky,
While the IAT may be part of the problem, in my reading of the literature that sensor is mainly involved in improving hot starting problems rather than running when the engine is warmed. Rather I would be suspiciour of the ECT (engine coolant temp sensor) which controls the mixture as a function of engine temp. You may have a ECT which is off calibration and thus not giving the correct mixture for the warm engine. It should read  7 to 14K ohms when cold, and 700 to 1,000 ohms when the temp is 200F. So consider changing that sensor first. The sensors can be off value but not enough to set a code.
