This post may help someone who is having issues with 3.8 v6 ecotec. I've been having some trouble finding the source of a rough idle in my 03 vy ecotec v6 for some time and have found the issue. It started as just a little burble at idle every now and then and kept getting worse. After changing all the easy items, plugs, leads, coil packs and ignition module, it was still idling like a cammed up ls. The problem was only at idle and fine when driving. After many hours searching the forums I removed the plastic cover and with a tin of throttle body cleaner sprayed around under the plenum until I found a spot where it changed the idle of the motor back to smooth momentarily.
After removing the gasket between the plenum and intake, I found the paint like covering has been cracked and leaking. After replacing the gasket and plenum cover o ring, back to a nice smooth idle.
I hope if someone is having the same problem that this may help too. Only a small crack in the lining but once replaced had my old girl singing like she used to.
