Mulkey

A strange noise is coming from underneath when barely on the gas. A rattling noise. Nothing when in park and hitting the gas just when the car is moving and barley touching the gas. Muffler/exhaust pipe????? Pretty freaking loud. What's everyone's best guess? Just got it back from the shop- new timing belt/water-pump/shocks-springs/bushings and spark plugs.

I actually heard it before the work was done but now it seems louder. Maybe the exhaust heat shield????

yeah i agree those dang muffler bearings gotta watch those cause when they go it usually messes up your piston return springs

I just filled up the muffler fluid so I doubt it's the bearings.

That's what it sounds like or the heat shield rattling and it's coming from that area.

have someone drive very slowly so you can walk beside it and listen for the noise. Try to determine where abouts its coming from, ie, front, middle, rear, higher, lower. Also, if the noise changes with increase in speed.
