I had the same problem with my 2001 silverado 4.8L ext. cab. Chevy had trouble with the I.A.C. (Idle Air Control valve). Carbon-soot build-up rsulted in rough idle and at times stalling. The entire system had issues, MAF (mass airflow sensor), TB (throttle body) carbon build up, intake manifold gasket leaks. Depending on how many miles are on the truck, try replacing the IAC valve. This controls the idle sped at a stop. Also try cleaning the throttle body bore and butterfly plate with throttle body cleaner. Replacing the IAC will result in a rough idle upon start-up. The computer will have to "relearn" the correct idle speed after running for 15-20 minutes while in park. My 2001 drove me crazy with rough idle problems, had the dealer reset the computer twice to the original factory settings. All started around 60,000 miles. Good luck, I've worked on chevys for over 20 years and have built several engines, This rough idle / stalling issue has all owners very angry. One of chevys brillant ideas to control carbon-soot build-up, redesign the PCV valve and remove the check valve inside to improve vacuum flow....HUH? Let me know how things work out.

Make sure your air filter is not clogged and the air box is unobstructed. squirrels love to build nests in the tubes.

Idles roughly, then low when stopped or in park, then dies. Decreasing gas mileage. Slow to accelerate


Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

2000 Alero idles low and dies when stopped.


How does it idle when you first start or idle when hot.
On the top of the air intake tube there is a small screw which should when screwed in speed up the idle and if it dosent work or it idles fine when cold or warm at idle then its your GEARs are binding up and there's not to much you can do about that ........sorry

your idle speed too low.take it to a dealer.they have to reset idle.it should be 600-800 rpms.when you turn on air conditioner.the computer steps up idling to keep engine from stalling .your curb idle too low.
