my 03 4.8L 2wd silverado wants to die on me when at idle and when im decelarating from high speeds or going around turns. The battery/alternator are good and it starts up everytime just fine. I talked to some mechanics and no one seems to know the problem. Any help/suggestions is greatly appreciated. --Thanks

how many miles? original spark plugs? maybe a computer problem, or dirty fuel injectors.

make sure you're getting fuel. check the fuel filter (is it dirty/clogged?) make sure you have no leaks in the lines, fuel injectors (everything in the first post) maybe your fuel/air mix is off?
