i could use some advice.... I bought a 2014 GMC Sierra crew cab z71 4x4 and my check engine light flashes so i take it to the dealer. Truck has 5k miles on it. Dealer says it is a misfire on cylinder 8. They tell me it had a loose clip on the spark plug. 500 miles later the check engine light flashes again. Go to the dealer again its a misfire on cylinder 8. They replace the plug and the wire. Said it was a bad plug. 500 miles later the light flashes again. I call the dealer and they tell me they will have to teardown the enging to cylinder 8 to see what the problem is. Does this sound right for an engine with less than 7k miles to need a teardown to cylinder 8? What does that all consist of anyways i ask? The serive guy never gave me a straight answer and wouldnt tell me what the compression was on that cylinder. I dont like the sounds of teardown a new engine and asked for that coil pack to be replaced and was told no. Anyways anyone had any problems similar to this and could offer some adive or tell me what a teardown to cylinder 8 consist of? Thanks
