    My 2003 silverado 6.0L stalls when making sharp turns or parking. The RPMs also go down when I let off the gas. At first I thought it was an electrical issue but I've had the alternator and battery tested at auto zone and there both working fine . I going to clean my throttle body next. Does anyone have any thoughts?

    my 03 has the same problem clean the throttle body very well with carb cleaner and a tooth brush. grab a rag and wipe it slean. if u have an aftermarket cold air intake. my k&n gets dirty every few months. take a damp rag soaked with carb cleaner and clean the intake piping and spray down the MAS. check ur air filter too. works every time. for my truck that is.

    I took apart the throttle body to give it a good clean, looked worst than an old chimney inside. Once cleaned all issues with stalling and power issues went away, drives like new.

    It could be a faulty Idle Control Valve (ICV) and some of the time cleaning it will not solve the problem, it may need to be replaced
