97 TJ wrangler 4 cyl Rough idles low compression

I have a 97 tj wrangler that all of a sudden started running rough on a trip, I took it to a mechanic who said one of the cylinders had low compression and the engine was no good. What I dont understand is that after changing all the spark plugs, cap rotor...it still runs rough at idle but it wont stall and even though it has less power and will still run for long distances. Could this be a valve problem or an electrical problem. I cant believe that the engine could just go like that and it still runs fine now just without power and rough idle. Any help out there???

Any explanation for this? Low compression - while potentially a serious problem - doesn't absolutely mean that the engine is "no good."

If it's worth doing, then it's worth overdoing.
