I have a 2003 Silverado 4.8 L, two days ago it started idling to slow and dieing. Not getting any error codes. Checked the fuel pressure regulator seems ok. Runs good with plenty of power, just wants to idle down around 400 RPM all the sudden.
Any Ideas where to go next?

mine did that for about a month before i really figures anything out. i got a few error codes, and the truck idled horribly. my battery was fine, plenty of power, but once in awhile, when the truck was idling low, i noticed the battery gauge would move around. i replaced the battery just to see what would happen, and it's been fine ever since. if you can get a hold of a new battery to try for a few days, maybe that'll help. it sounds dumb, but that's what worked in my truck.
