Rough idle in drive but only when sitting at a stoplight

[VX KAT]

Hmmmm, vibration/growling sound.....could it be what I'm having??...where something along the exhaust system is touching the Kilby skid plates? Mine rattles and growls when in Drive, and brakes applied at a stop.

It developed during my road trip. Jack and Dub both pushed/pulled on the muffler and some other exhaust pipes and it stopped. *Of course it's hot so be careful when you grab around there.*

I haven't had it evaluated yet.

Could very well be. Maybe I'll crawl under the VX and take a picture of the top (inward facing) side of the plates to see if there's any shavings or scratch marks. That's a pretty scary thought. Maybe if I drop it off at the mechanic tomorrow afternoon I'll get an answer for you guys.

And thanks for the reassurances Marlin and Dub, I'll pull those fuses tomorrow and see what happens.

Been under there with my own eyeballs, your problem is that the pas side (IIRC) exhaust makes contact with the kirbys...maybe a few washers between the frame & the skid plates would work?

You said it was a grinding rubbing sound you could feel through the brakes. That is not the same as a rattle/vibration. There are so many heat shields on our exhaust, I have methodically removed them as they start to rattle. I have one left, and I had to remove the one above the transfer case as well. No more rattles
Mine only rattle when the brakes are on and I am sitting. That is your problem...a fast tink tink tink sound. Very annoying, but doesn't hurt anything, put it in neutral or start moving and it goes away.
