Knock Knock!!!

[Love-my-LSV8]

Can anybody help me here? I have a 2002 LS V8 with about 22,000 miles on it. I use 91 octane gas all the time and when I accelerate quickly off the line I am getting some knocking from the engine. I have tried fuel injector cleaner to gas line cleaners. What do I need to do to get rid of this problem? Will the dealer help me on this since it is due for an oil change soon?

I dont think the dealer will help with anything unless you pay them to diagnose it. The easiest way I have found to cure this is to disconnect the battery over night and your knock should go away. Your PCM may need to reset its learned parameters.
