Replace spark plugs and coil packs Now battery lights on and keeps dying why

Thank you for your input I bought the coil packs at amazon.com I paid $65 for a set of eight instead of $98 a piece from AutoZone are you comfortable buying coil packs of that price

Thank you for your response I bought the coil pack amazon.com for $65 for an eight pack AutoZone was $98 a piece are you comfortable buying Amazon at that price and do you have any feedback on the product from Amazon

yes,that's a good price on them if they are DENSO 6731303 OEM COP's. RockAuto.com has the DENSO 6731303 OEM COP's for $53.79 ea plus $7.89 shipping,2-3 business day,for a total of $438.21 no tax. even though amazon was almost 100 bucks more than RockAuto,it still beats AZ's LARGE MARK UP PRICE of $86.99 plus tax..

I love Amazon! only good things for Amazon because I have the Prime and they will deliver whatever I order in 2 days(free shipping),even if it falls on a Sunday.Right now USPS gets paid by Amazon to deliver on Sunday,but the more I read about them,soon they will have their own delivery service.If everyone had a crystal ball,lots of folks would have made a ton of money from buying their stock because a little over a year ago it was around $800.00 per share,today it closed out lower than it has been because of a dummy's mouth,but still @ $1493.45 per share even though the DOW dropped 420.22 points! anyways,as pushrod stated,check behind the work that was done,see if anything is disconnected/broken to cause your battery light to come on.good luck....
