Tried a search and found some info that it may be air in the coolant, but not sure as I hear it from the muffler.

I think the problem started (or became noticeable) after I lowered my base timing to 15 degrees from 20 after finding out that my enthalpy tune should be set for this. So at idle, the sound from the muffler sounds like it's gargling fluid, like a bubbling sound. I'm going check to the coolant, but could it be something else?

After adjusting the timing, it also tends to bounce between 16 and 15 and the idle kind of dips a tad so it's not smooth. Not sure if this is related to the sound.

Thanks
