[QUOTE="Silbult14, post: 16104581, member: 179221"] Don't be too quick to decide #8 is shot. A bad coil pack on that cylinder will cause a misfire and oil and carbon on the plug. Try moving a coil from one of the other cylinders to #8 and putting the #8 coil to wherever you got the coil from and see if the misfire code changes cylinders. If it's still #8 then a compression test, leak down test and bore scoping it would be in order. If any one or all of these three tests indicates a problem then a tear down is the next step. If all the other cylinders check out good, just fixing #8 might be OK, but considering the mileage and not really knowing about the first 85,000 miles a complete rebuild might be in order. Another option would be a low mileage used engine with a warranty. Several years ago I bought a 3.8 six cyl. with 52,000 miles for my old '01 SN95 DD from LKQ for $550.00 with a six month warranty. It's still going strong now with over 200,000 miles on it. I am sure a Coyote will be a good deal more, but it might still be cost effective. [/QUOTE]
