Sorry to hear,I have a 010 Silverado with V8 that drops to 4 cyl.when it calls for.Never heard it being a issue. I would call GM. something wasn't right from the factory on your motor. I have 70,000 miles on mine and runs like a watch. I installed a Jegs motor. " Long block" in my brothers 2005 Dodge last year.small V8. Time we were done he had around 5 grand in it. With free labor
