How To Swap Injectors On a 350Z | Did This Fix Our Car?

[@jakes2365]

Thanks for posting this. Currently troubleshooting a rough running on my 03. My long term fuel trim on bank1 is stuck at about +10% and I did have a #5 coil that seemed to be acting up. After the coil & plug replacement the fuel trim is still stuck leading me to believe maybe the injector is sticking closed or weak. I only end up with a random misfire fault after long rides. Did you have any faults leading you to finding cylinder 5? Thanks for your time

So glad I found this video. My z just started doing this last week!!! Replaced plugs and all coils are good and still sounds like a subie. How did you turn off the injectors to narrow it down? What scan tool did you use?

It was a snap-on scanner but you can also achieve the same results with an autel scanner.

Mine just threw the EVAP code... No idea what's going on. It misfired and then stopped. So I bought some new spark plugs and coil packs and go from there

Where’d you get the new injectors from?

[@Hello-pl2qe]

Did you ever have a pending lean condition code or hard fault code?

[@velocitygarage]

No codes but since then it has cleared since I drive the car more often assuming it was an injector just clogged

[@RileyWuzzHere]

How’d you know which injector was faulty?

[@DominicZido]

u can do a positive negative wire method by hooking 2 ends of a wire to positive and negative terminal on battery and then touching the sensor from the injector with them. if it sprays they’re good if it doesn’t u found your problem. is almost like a crank test without having to crank

[@velocitygarage]

Trial and error lol

I have a strong exhaust smell . You can smell it bad . Also when I’m parked . You can smell it from the inside . Could the fuel injectors be the problem ?

I have the same issue I replaced everything except the injectors now I’m going to try this also
