Thanks for the help that does help me out I have a number four injector not working but I'm thinking about just taking them all out putting new O-rings on them or go to the junkyard and get someone there
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!
For my 2007 Liberty 90,000 miles was the Injector electrics. For some dumbass reason I didn't ohm the #1 Injector leads. When i eventually did, it ohmed at 148 instead of around 12.5. So that explains why I had low rpm misfires under 500rpm. Likely upon startups, bc it started and idles fine. Doesn't miss otherwise. Bought reman Denso 6-pack on ebay for $72. I'm just replacing that one Injector #1 bc I'm like that, so I'm gonna try to do that without having to remove anything but the #1 and #3 coils and fuel rail bolts on both sides. Maybe the air intake if necessary.
Disconnect the battery or remove the fuel pump relay. Start the engine to consume the fuel until it shutdown. Later on passenger side, there is a purge valve located in the fuel rail, similar as the tires valves, push the pin to discharge the fuel pressure on rail if it is presurized. Regards.
05 jeep liberty limited was running fine started it up took off got to 25 mph stalled out! If I give it too much gas at once it will stall out and if I don’t let off the gas makes Jeep buck hard! Oreillys tester said #4 injector! I just installed new #4 coil pack a month ago checked coil pack it was loose tightened but still have the injector problem! Do I need to replace #4 injector? Tia
Turn to Jesus people, he died for your sins. Repent of what the New testament describes as sin. Believe the gospel get baptized and obey the teachings of Jesus. The gospel and the teachings of Jesus are documented in Matthew Mark Luke and John. Jesus is the only way to be saved, if you have faith in Jesus through your faith you will live by his teachings. God bless
Thank You, What a great tip on using an air compressor to clean them.

Great. What was the reason that You clean injector?
What can you use if you don't have a slide Hammer?
What year is this liberty?

you got 6 fuel injectors for 75 ;o omg i need that lol they tryna sell me 1 for 60
Release pressure from fuel rail or your have a costly part to buy along with additional labor
interesting "slide hammer"....but it works..
Nice slide hammer 🤣 i bet its steered you in the right direction!
One question, do you have to close the fuel lines and how. Thank you!

sounds like u need to replace the #4 injector
Had same problem it was the pcm. But start with replacing injector 4 first
Thanks yall i replaced the #4 injector and spark plug and coil pack and did node light test and got nothing so either wiring problem or pcm
I need to change six is it possible to just change one
I'd ask the injectors, they be honest people down there.
You can replace one but is generally recommended to replace all of them.
