I started my 2003 chev silverado put the truck in reverse and backed up. I noticed the check engine light was on so I shut off the engine, checked the gas cap and tried to restart the engine, but it did not start. There wasn't any electrical noise that the engine was trying to start. I came back to the truck 10 minutes later and it started right up. Since the battery was 7-1/2 years old, I replaced it. The check engine code was P0449, it is still on. Since then I noticed my door does not unlock when I shift into park, after about 15-30 seconds it unlocks. A couple days later I noticed that the shift indicator light does not immediately indicate the correct position that the shift lever is in. I believe all of these problems might have happened at the same time, I just didn't notice the shift indicator problem. All fuses are good, no visible damage to the charcoal canister. Help, out of ideas.
