Mary Christmas folks!
I have a issue which begins at about 4000 rpm, the engine makes a clicking sound under mild acceleration, sound to me like a lifter click or rod noise, which I doubt as the thing just turned 8k miles. If I back off the gas it stops and doesn't get worse if I hit it harder. Anyone notice that or have ideas? I've a '13 STS SE5.
