Question about 1995 Subaru Legacy
Car runs smooth, until I have to stop at red light or stop sign, then it runs rough. When I put it it neutral, it runs smooth. Could that be the EGR valve sticking? Any help would be appreciated, thank you.
I would check the vacuum lines first. I've seen many that no longer fully seal at the age of your car. The easy way to find the leak is to put vaseline on the ends of each one until the idle smooths out.

Depends on what you mean by rough. Could be a cylinder misfire.They sometimes are not noticed as engine speed increases during driving or under light load as when idling in neutral but at idle under load as when stopped at a light in drive became noticable.
Could also be running rich. The causes of either are too numurous to list.Consult a good mechanic who can actually see and hear the problem to put you on the right track.

mine did the same thing but was only a VACUUM line near the throttle body (like the carb) on top on the engine near the front of the car one of those line was popped loose u can just reinsert it but i recommend a hose clamp or even tightly use wire ties (nylon type) on all those vac hoses.
