I have a 96 accord, 2.2 mom vtec. This morning out of the blue it started idling really rough. When I accelerate the car seems fine but at idle it sounds really rough and did stall once. I've read some things about the egr valve and it being stuck open instead of closing at idle. It says to remove and plug the vacuum line that goes to the vacuum line but I don't know where the line is. Any ideas??

 

When was last throttle body service was done? if not then clean it, clean FITV and IACV

 

check for any and all engine codes

 

Yea there isn't any engine codes at all. I'll just start cleaning that stuff today and see how it goes.
