I have a 95 Civic Ex 1.6L with 170k on it. Just got back from a trip with it everything was fine till two days ago when the CEL came on. I was able to get the 17 miles from work to home. Took it out last night to see how it was and about 3/4 mile from home it started to run really rough and acted like it was going to stall when I came to a stop sign so I turned around and came back home. This morning we got a code 12 which is a EGR but my car doesnt have one. Anyone have a clue on what the problem is? We check the compression and it's fine.

Thanks
Michelle
