Wet slappy sound coming from engine at low RPMs when accelerating. - Toyota Yaris Forums

So I've noticed that my Yaris is making an odd sound. I have an AT transmission and when at low RPMs I push down on the gas pedal and a "wet slappy" sound comes from the engine. Almost like wetting your lips and making a low slobbery fart sound from your mouth... (I know, its the best way I can describe it hehe) It goes away completely once the RPMs come up a little. It can happen in any gear, as long as its low RPMs and I am pressing on the gas. It seems to get worse if I barely press on the gas rather than more aggressively pressing down.

I thought it might be the ultra-cheap ethanol gas I use, so the last three tanks I've filled it from empty to full with super premium no ethanol gas. Its still doing it.

Any ideas?
