View Full Version : Rumble on Acceleration

09-17-2014, 10:22 AM
Hey SC owners. Need some help. Will try to describe this the best I can.

I just recently purchased my third SC. It is a 1994 5-Speed and personally I think this car is in great condition. However, my concern is when driving the car and switching through the gears the car makes a rumble/baffled sound. It can sound like either the mufflers or the catalytic converters are going out. At idle the car purrs like the beauty she is. This sound is only on acceleration.

Can someone help me with this? Thanks.

My experience with bad cats has been that they rattle at idle. It sounds just like what it is, pieces of something hard dancing up and down. It's not real loud but very noticeable.
