Hello all. My girlfriend has a G6 GT with the 3.5L engine. Shes told me one day her car started to jitter and the check engine light came on then after a few seconds all was fine. We decided to hook the Modis to it and found it was a misfire on cylinder 1. When I asked about her spark plugs she said they have never been changed, the car has 50k miles on it.
I was wondering what type of spark plug these engines take? Platinum? Iridium?
I believe the stock ones are Iridium but they happen to be the most expensive out there.... what do you guys think? Can I install something becides Iridiums?
Also what brand do you suggest? I read Autolites are the best for "normal driving" but just wanted to make sure.
