Second time for bad coil pack

[robert cristiano]

My 2017 Tahoe again had a flashing cel and developed a bad idle and loss of power.
Brought it to the dealer who replaced #5 coil pack. The dealer explained how unusual it is since I am the only customer with these issues.

Check the spark plugs and wires. It is unusual, unless there is a LOT of resistance in one of the other components (plugs or wires).

Ask for your old parts back and check to see if it’s an oem or aftermarket part they replaced. A unintentionally dropped coil pack will also short life them. Check for cracks and discoloring on the coil. It is very odd however it’s very common to have a service writer make the comment about everyone else.
