Do you guys get a rumbling sound when you're in low RPM's (2-3 especially) and give it full throttle? Its a watery rapidly repeating sound. I drive a 2001 5 speed 3.8 and I've been thinking its normal. Do any of you get the same noise?

 

Watery... Rapidly repeating... Interesting description you got there lol. I get a rumbling sound though... My exhaust

 

Usually you get a sort of a sucking moaning noise if you don't have a noise baffle on the intake. Something like when a 4 barrel carb is at WOT. lol

 

air sucking in through the intake maybe?

 

Any SES codes? Check around the EGR valve. There is a gasket under it and if it is leaking, you will get some crazy noise but your engine will also be lacking performance. I could hear a vac leak with the hood raised but could not locate it. Engine was idling and I decided to spray it down, thats when I found the gasket cracked.

 

hole in the muffler or exhaust maybe? are u feeling any vibration when its doing this.

 

SES code says fuel trim too low in b2. I'll check for the leaks tommorow
