  1. Silverado Idling problems

    Engine
    Any ideas? I inherited a 2000 Silverado with a vortec 6 litre. Before receiving it, the exhaust was re-done and cats removed. The check engine system was disabled and cannot be read. When the truck is cold and in gear, the idle jumps up and down, and will eventually die. The idle is fine in...
