Jeep Grand Cherokee WJ 4.7 V8 4 Hole Fuel Injector Upgrade

[@alexandremacedo114]

meu WJ estava com um bico gotejando, o seu vídeo ajuda e anima a você mesmo fazer o conserto, aqui no Brasil as pecas alem de difíceis de conseguir são muito caras, mas para os amantes da WJ não ha limites, obrigado pelo seu vídeo.

[@getwrenching]

Thank you very much for your kind words. I really enjoy making these videos when I have the time. It makes me feel really good knowing that one of my videos are helping people out. Thanks again and hope to have a new update video of my old jeep up soon.

Appreciate the input. Changed my fuel injectors out. All is good!

[@getwrenching]

Sweet, good to hear.

[@abdelmoneamahmad7725]

did you use the same injectors he installed, do you have a part number?

[@rhondaedwards74]

What a difference! Wicked job! Keep up the great content.

[@getwrenching]

Thank you so much.

[@ericbryant796]

Nice job! I use NGK V-power copper plug in my '01 4.7L. They will go 50K easily between replacement. Never had to touch my fuel injectors yet, but looks like the 4 hole version is a good option.

[@getwrenching]

Been working very well with the 4 holes and I picked up a couple mpg. Thanks for Watching and taking the time to message. Very much appreciated.

[@abdelmoneamahmad7725]

do you have the part number of the injectors you installed? or a link?

[@brynnond.6952]

My 4.7 2002 wj does the exact same thing, noticed that fuel injector #1 has a crack in the casing but strange thing is, I straight piped it and now it starts great every single time, kinda confused like that because it definitely has a big puff of smoke and raw gas smell when starting, and my oil level slowly goes up over time from fuel dilution

[@getwrenching]

Change those injectors bud it made a huge difference on starting and fuel mileage has been great.

[@devenreal]

If that’s how the fuel is coming in to the rail I would strongly suggest you replace the fuel filter it’s located right behind the Driver side rear wheel

[@getwrenching]

Already done and it's a filter and fuel regulator. I replaced that first,it didn't work. So I did a leak down test to determine the fuel Injector.

[@CameronBlack-v6i]

Whats the best way to remove the plastic cap at 22:22 without damaging the injector?

[@getwrenching]

Best way is to work your pry bar around until you start to see some movement. Then continue this way until fuel rail is up and injector is free. Mine was stuck bad and original. Hopefully you have better luck then I did. Thanks for watching and taking the time to message. It is much appreciated.

I HAVE AN 05 WITH THE 4.7L , WITH 331 k , THAT THING RUNS VERY SMOOTH, I GET A SOLID 500 RPM IN GEAR , WITH NO SHAKES OR RATTLE...A BEAUTY. BUT ITS HARD ON FUEL, SO CAN YOU GAVE MORE DETAILS ABOUT THE INJECTOR YOU USED.....MAKE ,MODEL , SUPPLIER. I'M IN ONTARIO , SO I CAN PROBABLY GET THEM FROM THE SAME SOURCE. ALSO TRIED TO CHANGE THE EGR VALVE ....HAVE A CODE...BUT IT DOES NOT ACT WEIRD....EVERYTIME I TRIED A NEW ONE THE ENGINE RUNNED LIKE CRAP....I LOOKED AT THE JEEP PARTS LIST, THEY LITERALLY HAVE DOZENS OF DIFFERENT PART NUMBER FOR THE SAME ENGINE, TRIED 3 DIFFERENT ONE SO FAR THEY ALL RUN LIKE CRAP....SO I PUT THE OLD ONE BACK, ENGINE RUNS SUPER SMOOTH, BUT LIKES GAS A BIT MUCH TO MY TASTE....ANY SUGGESTIONS FOR THAT EGR VALVE ??? SEND ME THE INFO FOR THE INJECTORS IF YOU CAN. THANKS KEEP UP THE GOOD WORK!!!

They are still working wonderful but fuel millage still sucks. Its better but still not good. Your EGR problem is unknown to me as I haven't run into that yet with these and I did do some digging for you with little results. I hope this works for you and let me know what you find on your EGR. Thanks for watching and taking the time to message.

So my issue is i have a 99 with new plugs and coils but yet i have a misfire cyl 8 code. Would this be the next affordable step? Sounds kind of run and runs kinda rough. Thanks!

[@getwrenching]

Yes this is was my last resort so I did it and still running like a champ as of currently.

[@jat-justamaturetech-philpj8285]

Hi. I have a 2000 wj 4.0 I just replaced my fuel injectors with a 4 hole from a one hole, now im getting a code po172 and po175 bank 1 and 2 oxygen sensors, system too rich. Would this be normal for the ECM to reset for the new injectors after driving a bit, or is my fuel pressure regulator not adjusting to the new injectors? I replaced my fuel filter 2 years ago. Not sure if its a regulator fuel filter type?? Isn't my regulator on the middle of the fuel rail?? Thanks.

[@getwrenching]

Its hard to say but sounds like the fuel pressure regulator has left the chat. I would replace it with new and see what happens. Sometimes the ecm in these years jeeps are subject to fail as well. Thanks for watching and your comment. I hope it helps you out. Let me know what you find.

[@jat-justamaturetech-philpj8285]

@@getwrenching My question is, why would the regulator and or the oxy sensors go bad just because I changed the injectors?

[@getwrenching]

So your regulator was probably getting weak before you changed your injectors. Your o2s are just letting you know there is a problem. The o2s aren't gone just doing there job by letting you know your running rich.

[@crosley62]

I'm glad that I'm not the only one to have major issues when doing the simplest jobs. Most of these KZbin mechanics never have any problems when they show you how to do something. Total bull shit.Its good to see a real video.

[@getwrenching]

Thank you. Very much appreciated.

[@prikbastrd]

Is that 6 inch lift on 35's?

[@getwrenching]

Yes it is. Rough country crap lol. Probably going to install 6.5 or 8 Iron Rock long travel.

[@prikbastrd]

@@getwrenching I have the 4 inch RC long arm lift, put it on a few month ago on 33's. Appart from maybe the shocks' lifespan the lift is surpassing my expectations.

[@getwrenching]

I had alot of trouble with the front control arm bushing. Ended up with core 4x4 control arms.

[@4x4offroaders]

Want to fix my Jeep lol i live in Nova Scotia
