I'm having coil pack trouble on my G13B as well.
When the engine is cold it gives a slight vibration at idle and misses when u try to rev in neutral
Then if I'm driving and I pull off from a stop sometimes it gives a lil backfire or "pop" in the intake.
The problem was most noticable with my old plugs. Extreme vibration and the engine was missing with anythign over 1/2 throttle between 1500 and 3000 and above 3000 was working fine. Since I changed the plugs it's only slightly noticable and mostly so when the engine is cold.
The mechanics here at work were checking the spark from each CP and the one over the #1 cylinder gave them a jolt so I think it may just be leaking. It's like $1900 from lifestyle.. what else can I do to try to get them to hold out a lil longer? Oh, and meh gas mileage SUCKS

250km from a tank.. and it's a 1.3
