cyl #1 misfire

[West Coast Canuck]

Hello from the west coast of Canada
This is such a great site. Great people offering suggestions and advice for those of us with limited knowledge. I did a little digging and found the information needed to begin narrowing down the misfire issue.
I changed the plug wires and the ignition coil, still running rough, wish I had looked here first, DOH. Going to check the injector coils for resistance tonight to see if that is the problem.
Awesome site

I am not a mechanic by any means, all of my knowledge has come from working on my 99 T4R, mechanic friends, my manual, and referencing sites like this one for help. I had the same issue a few years back. After doing exactly what you are doing my issue ended up being a clogged injector. At this point I was around 170,000mi so I just went ahead and replaced all my injectors, some may say that was dumb but I don't like to do things twice, so when I have something apart I repair what I can get to if I have the funds. By the way, you can get refurbished injectors and take your old ones back as a core if this ends up being the same thing.
Good luck

Air, fuel, compression, spark. Misfire mean one isn't happening. Just be sure you identified the right cyclinder. Year and engine would be really good pieces of info. Help us to help you. After all, we're all in this together!
Good luck and keep us posted.

What year and motor?
FYI an injector can have proper resistance and still be faulty. You didn't mention spark plugs? Tell us what it looks after you pull it. How to Read Used Plugs: DENSO Iridium
