Low idle?

I had this problem and followed the guide worked perfect! I love this site.

I have a 2003 Silverado 5.3L 4x4 with 76000 miles. After having a dead battery, I am having problems with the idle speed being too low. It will stall going through slow turns and after coming to a stop. RPM's are only at about 275-300 or even lower. Is there a way the computer will "relearn" the correct idle speed? Will a scan tool be required instead? Other than the low idle speed, it runs well with no fuel smell or missing.

My 03 Silverado started acting up again. A year ago I had this problem and it mysteriously went away after a few weeks. A few days ago it started the low idle and power loss again. I thought the battery was no good, charged it, still the same prob. I thought ok maybe its the alternator, went down to the auto parts, got one and popped it in. That wasnt it either. Now it seems like its just getting worse. I start the truck and it immediately idles down very low between the 0 & 1 rpm mark and then just dies. If I dont hold the gas peddle down it wont stay running. If I turn on the air conditioner it just sucks all the power from the truck and it will die even quicker. Lights will dim down as the idle drops lower.
I havent tried taking it on the road since. Strangely when this started my oil pressure gauge began working and then not working. Now the "ding ding" noise when I leave the door open or the key in the ignition is working. I recently had the plugs & wires, airfilter and oil changed and it was running fine after the service. I have heard of this problem from others with a 03 Silverado, any suggestions?

Get you some intake and throttle body cleaner and a baby bottle brush and take off the air intake and clean out the carbon build up works great my 03 was doing the exact same thing I changed the alternator and battery and still the same thing. $230 later I pick up the $3 bottle of cleaner and it did the trick live and learn

Thanks for the advise. I got some cleaner and sprayed the maf sensor out yesterday. I will try cleaning the intake too. I did put in a k&n air hog air filter just before this started. Some say not to use those filters because of the oils on it. I used it in my camaro and my motorcycle with no probs, maybe my truck is just picky. Thanks again. I will post results. L

I changed my oil the other day and while my hood was up and I went inside for a drink my 6 year old son "washed" my engine for me. Luckily the cap was on the oil fill. However now I have a very low idle and the engine dies when I am turning sharp at slow speeds. The idle picks up a little when the A/C is off and the truck is in Park. It runs fine on the hwy just rough at low speed and at idle. On the bright side my engine is very shiny!

MY 03 SILVERADO IS DOING THE SAME THING. PLEASE LET ME KNOW WHAT YOU FIND OUT.
THANKS,

I have a 2003 Chevy truck, 75,000 miles, auto trans, 4x4, 5.1 engine. Two problems occurred simultaneously. My battery died, completely dead. Upon testing the battery and replacing it and then starting the truck, my idle is so low that the truck will not continue to run at idle. The idle is about 300 rpms when the truck is fully warmed up and usually the truck stalls. If the vehicle starts cold, it runs fine until it warms up. Any ideas? Thank you.

No check engine lights. Also I have driven the truck about 3 hours.

Thanks you in advance

While driving my engine runs fine, but once I come to a stop or if I slow down to turn it drops to a very low idle or even dies. I've replaced the plugs and wires. And a friend of mine hooked up the scanner and it comes up with (purge valve & cataylic converter). Could something besides these two items be causing the very low idle and those two items to show as defective? I do not get a check engine light.

When the truck is in Park it idles fine. It's when I'm coming to a stop to turn or just to slow down for traffic.

After hitting the 80,000 mile mark my truck now has issues maintaining low idle. The truck wants to idle about 500 rpm. The truck will even stall when in reverse. Is there a way to check the computer setting? Could the computer be off or sending the wrong information to the engine? Can it be reset back to factory setting or can the idle be adjusted?

my battery died. I got a jump and now my truck runs fine but idles @300-400 rpms while sitting still. Feels like its going to stall, what is going on?
