Default Rotten Egg Smell..Bad Vibration.

While driving around tonight, i notice my car has a real bad vibration going on. It shakes from corner to corner inside the vehicle, when WOT it gets horrible in higher rpms. Could it be my driveshaft? Maybe my UV Joints?

I know the rotten egg smell is from the cats being clogged up, but im replacing them with a h pipe im ordering in a couple of days, could that cause the vibration?

have you taken your drive shaft out right before you started feeling the vibration?

Did the problems start at the same time? Could be fuel related.

sounds like you are running rich. Thats what 99% of the time the rotten egg smell is. Have that checked out. Especially with the vibration. Seems like maybe your not igniting the fuel. Missing. Check to make sure all wires are in good shape and away from the header/manifold. When was the last time you replaced the sparkplugs? Any cracks in your dist? How is the coil?

I checked some things out today, found no vacuum leaks. I looked at my spark plug wires. and on the driver side. the 3rd spark plug looking from the front of the car , the wire isnt fully onto the plug it looks like. You can perfectly read the Bosch brand on the spark plug. and of course i tried minglin with it and stuff but it wont go any further

Looked more into this issue, got underneath the car and saw its leaking some kind of fluid right past the catalyctic converters are. I havent been able to see the color of the fluid or anything, im all dressed up for stuff. It looks like a purple fluid also. I'm thinking maybe its not leaking from the exhaust, but leaking from the tranny onto the exhaust? I do have to rebuild the tranny, im doing that next week.

I'm thinking the shaking and the smell are comming from the verts, if it IS leaking from the exhaust, could it be my cats are stopped up?

misfiring, egr valve issue, etc. Check your plugs and look for signs of a lean or rich condition, it will be very obvious

deffinatly sounds like the cats are causing the smell and vibration. one may have burnt up and it's causing some back up in the flow of the exhaust, which will make the system vibrate
