Fuel injectors are computer controlled spray nozzles that deliver fuel to your engine in precisely controlled volumes. They are one of the keys to modern efficient and clean engines. If a fuel injector is dirty or failing, it can present symptoms such as rough idle, engine surges, rich or lean conditions, and check engine lights. Replacing a problematic fuel injector with an engineered to fit TRQ replacement part right away is essential to the health of your vehicle’s engine. This video shows you how on your 2008-12 Jeep Liberty.

So you removed an o-ring from the fuel rail but didnt show replacing one.

Gary Harris says:

Have code faults for #1 misfire, fuel injector 1 circuit open, and Bank #1 lean.

There is a slight rough idle, but no misfire perceived, and it runs fine under load and high speed. Doesn't burn oil. Gets 15mpg combined mileage. Ran fine when I got it 64,000 miles. Now it has 110,000 miles. It has had this issue for about 10,000 miles. Not getting worse, but so far plugs and coils and cleaning intake hasn't corrected it.

I checked and cleaned Injector and Coils wiring connections and they look good too. #1 Injector plug had some oil in it, somehow. Cleaned it very well with first brake cleaner, then electronics cleaner. Let it dry and reassembled.

Can bad Injector o-ring cause this? I already ruled out spark plug, coils, valves, and did intake cleaning.

I have not checked orings and the wiring from #1 Injector to the computer control. And don't really know how to.

Any tips on checking Injector and its wiring and control while it's still in the head? Thanks!

Alright, watching this i wonder, if you pull all the tabs off each of the 3 injector connections to the fuel line, you pull up on the fuel rod to get one injector off…..you would be lifting the rail off the other 2 injectors. So wouldn't you have to replace the rubber O rings on the other 2 injectors as well, they would either fall outta the rod or be stuck up in the rail right?

How many inyectores it’s have Jeep Liberty 2005 ?

“You don’t want anything getting into your engine”

….proceeds to shove shop paper towels into engine injectors….

I would REALLY love your opinion! My daughters 2004 Jeep Liberty had misfires about a year ago and i found the plugs to be slightly loose (of all things) and it needed a couple coils! I replaced the plugs and coils and it ran flawless until today! The misfire started again with a check engine light and the code p0304! So, i went to the 4 cylinder and checked the coil and plug. Just for the heck of it, I replaced them both and still misfires!
To ensure it wasn’t another cylinder throwing the same code, I left the 4cylinder assembled and than unplugged each cylinder one at a time! In each case, the car barely ran! This tells me it is in fact the #4 cylinder. I pulled the plug and noticed it is not wet with fuel! This tells me that if it’s not firing it also is not getting fuel?! So, injector? Or the electrical to the injector?

Would you mind giving me your best guess?

If you’re able, thank you very much!

The best to you!

Changed #5 injector in my 07 Liberty . Was chasing misfire with Plugs , 02 sensors , coil pack switch from cylinder to cylinder. Nothing worked and the Cylinder #5 misfire continued . Then someone told me to listen to the injectors [ i have a powered set of listening headphones] , and sure enough no clicking from #5 . changed after watching this video [ a few issues getting it out and getting it to seat again. make sure you clean the hole real good…. lots of buildup ] . cleared our codes and drove it for 20 minutes , and she idled like a dream . Use the listening trick [ can even use a long screw driver against the injector and put your ear against the other end. should hear a consistent clicking.

Similar for 2007 3.7L Liberty? I have 102,000 miles. Time for tune up.

Chrisman Unboxed says:

Awesome details to details on breaking them down. Awesome job!!!

J Bryant says:

Thanks. I need to replace #4. When you pulled up on the fuel rail at #2 injector, did it also pop off the other injectors? If so, should I put a little grease on all when the fuel rail goes back on?

Macadoooo says:

Would it be ideal for me being cheap and just changing the o ring seals or don't chance it and while I'm down there just to get new ones?

Thomas Moore says:

Thanks for the video the injector you replaced is the one that I need to replace number two cylinder awesome job

Jim Stadick says:

Really really great video. Gave me the confidence to tackle a job I otherwise would have probably shopped out. And excellent call mentioning the little hook. I picked up a cheap one when I bought the injector and needed it for two of the o rings. Thanks!

BlueDually4x4 says:

Really well done video. Just straight and to the point.

John says:

Can I verify? I need to change injector #2. This should be front/passenger when facing the vehicle? Same one that was replaced in the video?

Andrew Montgomery says:

Changed my plugs and coils. Still have an intermittent misfire on #1. I'll change out the injector now and go from there.

mike v says:

Great video. Excellent quality. Thanks for "how to undo the clips and connectors". That is often a problem .

Chris MBA says:

I have been chasing down a P0304 code; coil packs, plugs, checked valves, rockers, lifters; ran a head gasket test, compression; etc etc. NOW I think I know the issue! THANK YOU!!!

Update: Performed this maneuver with fuel injectors I got on Amazon (Polemotor; about $12ea in a six pack) – SOLVED my misfire issue; drove it hard for a day just to make sure.

Igor T. says:

Great video. ! Great job ! Thank you !

mike b says:

Was hopung you could tell me how much in labour id be looking at to replace one of these?

James Reyes says:

You guys are very helpful always and have the best videos out there.

Eric Newman says:

Thx for the video. I tried changing my bad injector but It wont come out. Any tips trying to get a stuck injector out. I'm afraid to use too much force. 2006 jeep liberty. Thx again.
