Had a code showing misting in my 4th cylinder, had next to no acceleration. Coil pack arrived in 2 days (today) and now my 2004 Saturn Ion runs smooth again. Saved me 135$ by not getting my mechanic to order and install. Super happy, thank you. Now 2 months later coil pack has failed. I would like a replacement as a 2 month life span is absolutely horrendous.
