My 03 Ram here recently after a battery change has suddenly decided that when I am slowing (let's say at a stop light) or am at low idle, the engine shuts off if I don't keep the accelerator down some. It will fluctuate 200-300 RPM on it's own and once I let my foot off the gas at a stop there she goes. I detatched the battery cables and re-fastened the battery to ensure the cables were not loose.
I had a auto parts store guy plug in the diagnostic machine and the only the code that came up was (dont have the code with me) "ECM/PCM key not programmed". The AMPS/Voltage were fine on that check, alternator and charging system were both ok too. I went to the dealership to see if this was simply a short when I changed the battery and if it was a simple fix like just reprogramming the ECM/PCM or more complicated. He looked at me like I was speaking a different language.
What is your opinion? Thanks.
