I just bought a 98 Integra LS with 72,000 miles about a month ago. Out of nowhere the engine is idling rough from time to time but almost quite often. It's an auto tranny, when I put the car in D, the engine run smooth but a lot of times when I put it in N or P, the engine starting to idle rough.

Any advice on how can I fix this problem? Thanks guys.

 

It's been few days of the rough idling & now the check engine light is on. Any input guys? Thanks again

 

Did you pull the code?

 

No, not yet. It just happened, that's why but the rough idling been going on for few days or even the whole week already.
