Spark plug not firing?

Does anyone know if any lights would pop up if one of my spark plugs wasnt firing? When I put the #8 coil plug on it didnt have the feel of the other coil plugs (the snug fit when I put it on) im wondering if maybe thats why my MPG is so bad?

Re: Spark plug not firing?

I have had a similar problem - if the spark plug in question is a slave to he master then no code will show up! My local 4x4 guru at the garage spent a number of hours trying to figure this one out...
