08 Civic idling rough, revving high
I have an 08 Civic LX coupe with automatic transmission and 65K miles. About 6 months ago it started idling rough and kind of trembling/shaking on startup. When I backed out of the driveway and put it in D and gunned it up the street it would pretty much immediately go away. Replaced air filter and ran a fuel treatment through to no avail.
I took it to a mechanic and he said he didn't think there was anything wrong with it, said the computer was very sensitive and it would throw a check engine light if anything was wrong.
Since then the rough idle has gotten worse. Sometimes when I start it my keys even start shaking hanging from the ignition. And I have also noticed that quite often it seems to be revving higher than it used to before it shifts gears.
Any idea what might be going on?
