Maybe what you're experiencing is the infamous marbles in a can syndrome?

The water might be from the AC condenser or an oil spillage when you removed the oil filter, it might take some time for it to drip down.

Many forum members get that and some even claimed that by using higher grade gas will get rid of the sound. I don't see how that would get rid of it since it's water in the heater core.

i had one like 2 weeks ago, and i went to autozone and they told me it was a loose gas cap, i tightened the cap and reset the cel and everything was fine till 2 days ago with the sound and ****.
yea if it was just misfiring, i'm gonna order new coils and plugs and take it somewhere else.
thanks guys... i'll get an update in abt 30 mins, let's see what they have to say.
i'm gonna see if they charge me 900 for a plugs and coils change! lol

I have a feeling that it's your heater core. Go and grab a set of headphones or something, plug it in and see if it sounds the same.

It's really not a matter of maintenance or not, he only put about 6k on it ever since he bought it.

yea... Renesis SE3P, i'm home and i looked at the video, and it's definitely not that noise.
the dealer quoted me for 515+tax for replacing the plugs and wires. plus they found out i have a weak engine mount, but that's under warranty.
i'm prolly just gonna go ahead and order plugs, wires and coils and change it somewhere else and go back to the dealer for the mount. (uh... would they still change the mount for me if i go elsewhere for the plugs and stuff?)

do you guys know where i can get hold of those things cheapest?
thanks

thx for the reply dozer

hm..... is it really possible that the lower octane gas is causing this weird idling and spark plug misfiring? cuz.... what happens when we add 80/87 fuel instead of 100LL fuel on Cessnas, it would cause detonation in the cylinder... and... thus misfiring as well... hm.... just wondering

You know what impresses me most about this video is that he has a full tank of gas.

^ but doesn't the combustion chamber works the same like a piston engine? it's still basically the 4 strokes, intake compression combustion and exhaust...

^We are just saying that a knocking from a piston engine is not similar to a knocking from a rotary. The engine make-ups are completely different.
