I have a 2008 Honda Civic with 65K miles. It’s started idling rough and vibrating just on startup when it’s been sitting overnight. This continues until I start driving up the road at which time it stops. I ran a fuel cleaner through it and changed the air filter, which was slightly dirty but not too bad. No effect. Then I took it to my Honda mechanic and he said there was nothing wrong with it. Any ideas? ---

Did you buy the car new or know its operating and maintenance history? Auto trans? Rough idle in P or D? I’d guess sparkplugs, but I think you have 100K iridiums in it. Edit: Not so easy to change. ---

I bought it new and it’s never had any issues whatsoever. Automatic transmission. It’s idling rough when I start it (in P obviously) and put it in reverse to back out of my driveway. Once I put it in drive and gun it up the road it goes away. I did mention sparkplugs to the mechanic but he said the plugs I had wouldn’t need changing until a tuneup at 105K. ---

Tomorrow morning, start it 20 minutes early and let it idle. See if and when the shake goes away or the check engine light goes on.
