hey, i have a 95 civic ex, and my car has a lagging problem. Happens mostly in first and second gear. I try to accelerate, and i dont go anywhere, like im not giving any gas. Sometimes it picks up late, and jerks a bit. My friend checked my timing, alignments fine, and my fuel injectors are ok, i use fuel injector cleaner, didnt do ****. I wanna use sea foam, but i was told that its risky. Any ideas on what it is? thanx
