Default Here is a Fuel Injector replace procedure.

Since I cant seem to find any threads or posts of how to remove the intake system I am adding a PDF that has the full breakdown including what to remove and what to ignore. This is for the magnesium plenum.

Why did you only replace one injector? I kinda figure if you have it apart have them all rebuilt. I think it is like $30 each when I last looked into it.

LaserSVT, what were your symptoms for 1 bad fuel injector and how did you know you needed to replace it and which on. Some times I get a rough idle on startup, but no check engine light or misfire codes on my ross-tech. Thanks

I had a good result running seafoam and BD (I think) through a few tanks with a p303 which I think was caused by the injector.

They are more than $30 each. I didnt replace them all because it didnt need them all and are not difficult to get to.

Missfire after 70% throttle. I used my Autel MaxiSys Pro to read the live data and find the issue.

South Bay Injectors quoted me around $30 each to clean and rebuild.
