Plan on replacing it...... Welcome to NICO!!!

[Q45tech]

Considering how little most current Infiniti techs know about old Q45, why would you even bother [risk your vehicles life] with anyone but dealer or a independent who has ex dealer technicans.

If it needs parts PEP boys must order and buy them from a Infiniti dealer anyway...................or use some generic junk or cheaply done remans.

Very Very few components are substitutable..............injectors are so critical and difficult to get to and replace PROPERLY [except for 1&2 in front].

"injectors are so critical and difficult to get to and replace PROPERLY [except for 1&5 in front]."#1 and #2 are in the front. #8 is also replaceable without pleneum removal.

[Q45tech]

Bad typing 1&2 ........are easier at the front. Yes some are less difficult than others.

However most experienced techs would [RECOMMEND] just pull the plenum and fuel rail to the bench to replace the fuel hoses and all gaskets at the same time.
