Texas tea? Is that what they call milky good? Lol I changed my oil ever 2moro miles.

 

Dang phone. Milky goo and changed oil every 3k miles.

 

with the additives(cleaners) etc, you put in your gas
i would change the fuel filter just to see maybe a cheap fix?

sounds like detonation to me, i wouldnt play around with that

can you log any of this? to see your a/f ratio?

maybe even check your spark plug gap

 

Yeah check your gap...since its carb check your timing .

 

How has anyone not asked what igniton controller you've got? MSD? Edelbrock? I'm willing to bet that it needs tending to, or needed tending to before all of this started.

 

i missed that he had a carb

yes i bet your right
the controller could be very good prospect to look at

 

If its edelbrock ur fucked:p they suck that's what I have mine was doing the thing but it was twinge to diesel on me fix gap on plugs fine for now...

 

Alrite guys. I forgot to meeting that I had a superchip flashpaq programmer. I Jus did a quick tune. now after talking to a few buddies they told me to set the superchip back to stock and drive it... The timing and detonation was fucked. Now after putting it back to stock. It runs like a champ. I wasn't supposed if it still making that dang noise. But nothing. Thanks for the help guys.

 

Wait...Superchips on a carbed LS? WTF is going on here...? Dude, get someone to legitimately dial the thing in. That's nuts.

 

This is an '07 avalanche right? And you carbed it? Certainly sounds interesting...
