Hey, I've got a buddy who just swapped a Jdm B18C1 into is 93 si hatch, and he never had this problem untill about 3 days ago when he returned from a road trip. The engine just kind of skips a beat. It'l be revving, then all of a sudden it'll just lug out for a split second and then keep going. It's the origional wires on 80k, so I told him to get some new wires. Plus I'm sitting here remembering working on a LS1 that had a similar problem that turned out to be old wires. Anyone agree?
