Misfire no code

[Haywood]

Changed my fuel injectors on my 5.4 2 valve and used mode 6 on my scanner and found cylinder 6 high misfire but no code. Wasnt there before the injector change. When i started it up #5 electrical connector tab broke off and became loose. I rigged it with wire ties and ran better. Still mode 6 shows high misfire no code. Has new ford plugs, cops, fuel filter, air filter, clean MAF, and clean Throttle body. Do you think the plug got fouled? Or is the scanner storing the misfire?

Bad plug imho!

I’ll pull the plug and check if it’s fouled and replace it. Think I should swap coils while I’m at it with another coil? Kill 2 birds?

...and if that doesn't work, swap the injector too.

Swapped coils and changed the plug. #5 still misfires. Tomorrow I’ll swap the injectors. Thanks for your input.
