Hello, i have a code on cylinder 3 fuel injector. I am going to replace it on my own, do i need to relearn the new injector or is it just plug and play?

thanks!

 

Below is my opinion, others may have different ones.
I do not replace fuel injectors myself as it can be easy to damage them and other parts when replacing.
Also verify the replacement injectors are the same as the OEM.
Some older injectors have been replaced by newer versions would require you to replace all of them for proper performance.
You will also need to replace the stopper ring, O-ring, back-up ring, and Teflon seal of the fuel injector with new ones.
Do not remove the fuel pressure sensor from the fuel distributor

 

The replacement fuel injector requires coding/registering with the PCM/ECU.

 

Thanks, I forgot that as well.
That is why it is best to have a trained technician do it.
