Misfire - Injector number 3?

[RichB]

Got another misfire. Only at idle though and as soon as you rev the engine it clears. I was going to swap 2 and 3 to see if it's the injectors as I had new coil pack and leads not long ago and replaced injector 4 not long before.

Code reader gives the following info

why bother swapping them over? just stick a new injector on.

Checking no one says it could be something else?

check the resistance of the injector, you're looking for 15-16 ohms.
