" My engine idles rough and oscillates badly when either in drive or a/c on in drive; when in neutral, it idles smoothly. I would like to know before the check engine light comes on. "

Our '08 sedan has done this since new . Replaced the P.C.V. at around 20,000 miles and no difference . Still idles rough when in gear at stops or idling . Fine when in neutral or park . The car now close to 58,000 miles .

Thought it might help with the rough idle . No difference . Not all that expensive or difficult to replace .

Just cleaned mine, it was a little clogged. Runs smoother now.

Checked mine. Have about 90500 miles on the odometer. Wasn't clogged, rattled freely. Cleaned it off anyway and put it back in.

lol. One of the bigger things right now on YW, I guess. Since everyone was talking about theirs, and since it's such an easy thing to check and clean, I just thought, "might as well." Also wanted to see the condition of mine after 90,500 miles.
