97 Dakota (3.9L) will another ECM help me ?
1997 V6 Dakota 3.9L 176,000 Km automatic trans
issue #1 - comm error unable to run a scan
#2 - various "hic ups" lately seem to point to ECM
maint (1) - i had an auto electrical tech work 90 min searching for the scan problem. He found no opens, shorts and bad wiring at connector port end. His conclusion was that my ECM was the culprit.
maint (2) - vehicle constantly stalls out, especially when shifting gears. When idling or in traffic it wants to hic up/burp and stop working, unless i keep the accelerator suppressed. Once the vehicle warms up, this problem usually ceases (but not always). I have replaced wires, igniton coil and plugs, as well as the temp sensor.
Speaking to another auto tech, he suggested i replace the ECM. Used ones are much cheaper (of course). If I do this, and get an ECM same year,engine, model, will it work okay for me(after it settles in and assuming it is fully functional)? I'm wondering if the Dodge dealer has to get involved with any updates, flashing, etc ? Because it's a 1997 vehicle, i would think updates have long since ceased.
If anyone could advise and assist, it would be much appreciated.
