Changed Spark Plugs on 5.7...now check engine light
Evenin' all. Changed out the spark plugs in my '08 5.7 today w/92000 miles on the originals. Ran fine before the change, runs fine now...but I've got a "check engine" light on the dash after the change. Is this a typical result of changing the plugs on this engine or do you all know of a trick that I might not have thought about when changing plugs today? Does this clear once the ECU "learns" the change in plug performance?
