I need a spark plug wiring diagram for my 1997 toyota avalon with a V6 model 3000

Had difficulty preparing the diagram. Here is a video: How to Replace Spark Plug Wire Set 95-97 Honda Accord - YouTube
I'll try again as you won't be amused by that. Cylinder Firing Orders & Engine Diagrams - AutoZone Hmm, still trying.
4 - 3 - 2 - 1 for the spark plug wire routing of a 1997 Honda
If you need more information on how to replace the spark plug wires on your Honda Accord, you can check out this video tutorial from 1A Auto. It provides step-by-step instructions for properly replacing the spark plug wires on a 1995 Honda Accord V6 2.7L, but the procedure is similar for all 95-97 Honda Accord V6 2.7L models.

Why are you looking for an oil solenoid. A misfire is only caused by two things

A fuel injection issue
or
An ignition/firing/spark issue

It appears to be a well documented issue on the Avalon. Take a look at the videos.

Also clean the Throttle body and MAF
