I have a 2004 V6 with 108K miles. It has been trouble free except the drive shaft bearing thingy problem that cost me $1600.

But today, the engine started shaking loudly while driving home. I didn't notice any problem till the steering wheel started shaking slightly. I thought it could be a wheel issue. But then saw the check engine light flashing on the tachometer (flashing not constantly lighted). I got out of the car and opened the hood and to my shock the engine was actually shaking and making rather loud noises. Got back in the car and drove home very slowly. The needle on the tachometer kept going up and down even though my foot was off the gas. It got louder and louder. The check engine light by now was lighted constantly not flashing like before. No more driving till have the car towed to the shop Monday.

Has anyone experienced this issue? Thanks.

If the cat is clogged you will most likely get horrible gas mileage. The car will overall feel sluggish. You can rent a generic OBDII scanner from Auto Zone for free. You can pull the codes with that. If it really is a bad cat i would skip the dealer all together. Go to an independent muffler shop. They can hook you up much cheaper. They might give you a hard time about it though. There are cat replacement laws. Read up HERE. Just talk to them though, they will do it.
