Engine Noise
So I noticed today that when my car is at idle that on the drivers side I have a knocking noise, like a lifter maybe or a fuel injector. And as you accelerate it speeds up and then disappears. Has anyone noticed or had this problem and if so what did you do? I have only run premium gas (93) and I used sea foam to clean everything nice and clean. Any suggestions as well.
Thanks Brandon

Yep, put a stethoscope on the first cylinder thought it was loud. Took it to the dealer and let the GM performance tech and GM heavy tech listen they thought it was just lifter drive train noise. Now after all that phobia, its no louder than the right. Just jam the throttle and quit worrying, if it turns out to be a lifter then you will know, but no since having the heads pulled just because you suspect...

True. I'm assuming it's just a normal ls motor noise.
