Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
hi this is often a faulty egr valve here is a few tests to do and let me know what you find
what iac codes are you sending to the computer ?
i have never heard of such a thing
codes are trouble codes indicating a problem , you retrieve codes form the pcm you don't send them
Perhaps codes was not the correct term to use. Essentially he is resending the program values to the computer for the IAC valve. It seems like these values are being lost overnight. I don't understand how these values are stored in the PCM and if it is possible for a storage location to go bad in the PCM like most other computers. If the problem is the PCM I will spring for one, but I also would rather not go that route if it could be a bad connector pin or ground.
yes they are known for this trouble , make sure the battery is new and the terminals are clean because any power interuption will cause a memory loss,
if that is all in order then you will need to replace the pcm
I will let you know the outcome. It will likely take a couple days to get a PCM.
Please be patient, as I mentioned it is going to take a few days to determine if your suggestion about the computer fixes the problem. I will not forget.
