Cylinder 3 misfire after track day
On the way home from racing I noticed I had a check engine light that wasn't on before I ran the car that day.. Autozone sez it'* a misfire on cylinder 3. They said either I need a tune-up, I have a bad injector, or dirty injectors.
I just did a full tune-up like 6 months ago....
Should I run some of that fuel injector cleaner through it and see if that helps? What else could be my problem :?

Is it possible that a wire is loose? I remember Peace having a loose wire and it caused a misfire, unless I'm horribly mistaken

pushing the ignition to it'* limits will also cause week components to go. You could very well have busted the plug or wire.

I pulled the plug, it looks clean as a whistle, and the gap was at .060. I kinda looked inside the wire, it.. SEEMED to look okay, there wasn't any obvious corrosion... I tried to smash it back on really well, they're tough to get on all the way :? Is there another thing that could be causing it? Does the dirty/ bad injector theory sound plausible?

Try swapping #3 spark plug with #1 & swap #3 injector with #5.
If the miss moves to #1 replace the plug.
If the miss moves to #5 clean or replace the injector.
If the miss moves to #1 replace the plug.
If the miss moves to #5 clean or replace the injector.
