Ok, so i just bought a 02 civic 5 speed, it has barely over 600 miles on it, and it seems to developing a rough idle. But it only seems to do it when at normal operating temp. Ive done a bit of researching on the web and everything seems to point to a bad o2 sensor. There is no movement on the tach to indicate the rough idle, but i can definetely feel it. Is this a common occurance after the engine is semi broken in? or do i need to take it back to the dealership for repairs?

Yea, take it to the dealer to get it checked. BTW, why do you think it's the o2 sensor?

 

Ive had the same thing happen on older cars previously and taken it in and turned out to be a bad o2 sensor. Im just a bit confused as to how a o2 sensor can go bad after 600 miles....

 

There are alot of causes for a rough idle. An o2 sensor wouldn't be my first guess.

 

take it to the dealership if you start wenching on it they'll void the warrenty
