Question about 1992 Hyundai Sonata

1 Answer

I own a 1992 hyundai sonata 4l2.0.,which I keep in Europe and drive it every summer.It has 56000km on it.Last summer it was running rough at idle and sometimes it wouuld stall when i put it into gear.Also, some black smoke came out of the tail pipe.My mechanic there changed the spark plugs and wire set but the problem is still there.This summer I will changed the PCV valve,as my mechanic here suggested and see what happens.What do you think? By the way how can I locate the PCV valve myself looking at the motor under the hood?Please advise.Thanks
