No scanner needed, just turn the key from off to run three times, leave it in run the third time and the code will show up on the cluster (where the odometer is). You'll see some dotted lines, then the code(s), and then "done".

There are only 8 plug wires. The remaining 8 plugs have the coil sitting right on top of them.

Some of them will miss at 60k, others will go past 100k and run exactly the same, but they're supposed to be changed every 32k as said above.

Good luck with it
