Smoking engine after coil and spark plug change

[john12312]

Thanks to all for taking time to provide feedback. Really appreciate the info.

I'll review the connections and replace the original plugs that were working fine before being replaced. Need to make a decision on a scanner. I like the price point and flexibility of the foxwell, but would like the added functions of the Durametric.. Only obstacle is my windows PC is old and needs an extension cord for power. Been using Macs for about 5 years now and have gotten used to them.
