I tried replying to this post once but it didn't take. The fuel filter is a good start but also check fuel pressure to isolate a possible dying fuel pump or fuel pressure regulator..... I would hook up a fuel pressure gauge at the shrader valve on the back of the fuel rail and measure for at least 37-41 psi at idle and more with vacuum. If that doesn't work it could also be some dirty plugs. If he's got headers you can change plugs in about 2 hours. If not be prepared for an all day event....

Yeah the optisparks are sometimes a PITA. It could be that but I'd check the other stuff first. Surging is usually caused by fuel delivery while stuttering is caused by lack of ignition spark. A swap to a new coil is also a good idea. It's not a bad idea to get an upgraded coil and they aren't that expensive at about 100 bucks for a top of the line Nology (I have one)... And the "dong" that you referred to to swap to a vented opti is more commonly known as the Cam dowel pin. There are two versions, a short for pre 95 non vented optis and the long for 95+ vented optis. I'm still trying to make sure which one I need since I have a 94 block but I have a 95 vented opti. I have all the accessories of a 95 that came off my old motor but the block is 94. It shouldn't matter cause the timing cover is the key so I shouldn't have any trouble mating up the cam to my 95+ opti. I have the long dowel pin cam but the one that came out of the 94 motor was a short pin cam....
