engine stalling

My '93 Civic LX has begun to stall more and more frequently. I added some fuel injector cleaner, but it doesn't seem to have helped. The electrical system checked out fine at the shop. It seems more prevalent on damp days. Suggestions? (note: I'm an extreme novice, so be gentle)...

explain more of your problem. does it stall while you drive? etc.

fuel filter ? try get a new one and see if it helps
