I've got a thread here about my OPDA woes and also I'm not an expert just try to read, listen and understand. Here is what I have gathered.
My understanding is that the dealer or someone with a Chrysler scanner needs to set the OPDA. I was able to move mine around and find a spot where the engine ran fine, at least didn't throw codes for the test ride.
But... I was told that the computer coordinates the fuel-air mixture based on the OPDA's data. That would mean for the engine to run right, beyond our seat of the pants assessment, you need to get the scan done.
