My 2013 Chevy Silverado was starting very very rough for about 5 seconds and then would run fine until the next cold start. Was getting many error codes, too lean, too rich etc. etc. Took it to the dealer and they suggested intake manifold gaskets and a new MEF sensor. Didn't help at all to the tune of $1,200 later. Engine light back on after the dealer fix and took it to Autozone to use their code reader. This time it suggested a fuel injector replacement so I thought to myself why not try a bottle of this Seafoam as I have heard about it before but never thought I needed it. After adding the bottle to 15 gallons of gas at the station and driving about 40 miles roundtrip in a day. The very next day it started perfectly and the light is now off. For a $5.00 bottle of Magic stuff!!! I sure wish I would have tried that before the dealer fix.
