Well I ordered a set of eight coils, may as well get it over with. I just replaced one of those things last week and I noticed another one acting up a little this week, those things are ridiculous..I guess it makes sense that all would act up at about the same time. I didn't buy a set of 8 on e-bay before because I would have had to wait too long, I was already getting a lot of shudder with that coil being so bad. I imagine the check engine light will light up by time I get the new ones, and if not it won't be long after. Thanks again jbrew for the info on those ignition coils.
