Update!!! Posted here a few weeks ago detailing a prob with my 2000 Ram 1500 4X4 QC loosing power, sputtering, misfiring and backfiring from the intake ONLY when cold. Well, I just took it to the dealership for them to keep until it was fixed and after checking w/them found that they have been able to re-create the prob but NO CODES. They said they called Detroit w/symptoms and were told to connect the recorder to PCM, drive and record then send the results of the recording to them for analysis. I'll let everyone know what they come up with, as I am grateful for the many suggestions and tidbits of USEFUL info I got from guys on this and other boards.
