I have 2003 tahoe and the battery went dead. Since I have not replaced the battery since the truck was new I assumed replace the battery. That did not work the truck idles rough and the new battery will not hold a charge (possible draw?). I brought the truck up to the local auto parts store to have them test the new battery and the altinator and they tested fine. I am at a stand still any ideas?

Try a battery parasidic which is something that stays on all the time whether the car is on or not, check all your electrical things to see if anything is staying on

I have allready had it in for Diagnostics and could not find a parasitic draw. They say the PCM might need to be reset? Can you reset a PCM?

Yes you can try taking the negative terminal off the battery for 5 mins and then put it back on this usually resets them
