My car has a "shaky idle", runs rich, and after it sits for an hour or so after recently driving it, it takes about 2-3 seconds of the engine turning for it to fire up(when its been sitting for a day or 2 it fires right up). Ive checked my fuel pressure and its fine, just changed my plugs on Saturday, and the wires only have about 2K miles on them. Is this more like a Leaking Injector problem(havent had a chance to pull the rail), or is it Opti related?

 

when my opti was going out my car started perfect, just when you drove it it ran like ****. It would be all boggy and would hesitate through shifts.
