I have a cylinder 4 misfire causing my car to go into Limp Mode, I have replaced my fuel pump, fuel filter, ignition coils, spark plugs and I’m planning on replacing the fuel injectors next. I guess I just need some direction because it’s my daily and I’m stressed as hell right now.

I only have one check engine light and that is the cylinder 4 misfire nothing else but it’s bad enough to where it won’t even start without going into Limp Mode forcing me to have to get rides to work now.

If anyone else has had a similar issue and can help that would be fantastic, I’m not amazing with cars I know some but I’m still very much new to all this.

Anyone change these? Just got an error tonight, and ordered parts for tomorrow. Looks like it is just a really tight fit to get plugs off....Any tips from anyone that has already done this and care to save me 2 hours of cursing for something that should take me 30 minutes (but that translates to 3 hours)?

Hi all. 2012 Jeep Liberty Jet that just hit 235k miles. I use the JScan app everyday on my 50min commute. I've had 0 misfire counts on every cylinder until this Tuesday. On start, cylinder 2 started hitting 60+ on the count. Mild rumble then smooths out a few seconds later. Count doesn't increase while driving, doesn't increase at a stop light for any of the cylinders. No smell, no white exhaust fumes, no stumbling driving or any other irregularities. I already had an appointment for tire rotations tomorrow and now having them take a look. Code P0302.

All spark plugs, coil packs changed a month or so ago. New wires, new battery, new throttle body, map sensor, coolant flush, purge valve. Oil change every 3000 miles or less. Coolant level is stable

Fuel injectors have not been changed. Any advice for self diagnosis is appreciated

Any chance someone can share a link to purchase a new ac condenser? Or whatever the tiny radiator at the very front is As I accidentally jabbed a hole in it and now coolant leaking.

EDIT: figured out what it is, transmission oil cooler. does anyone know where I could get one for cheep? ORiley’s has it for 150 and rock auto for 100. I’m not trying to break the bank right now but I also do need my car and the sooner I can drive it the better. Meaning I’ll probably bite the bullet and get it from orielys because I can get it tomorrow.

2006 Jeep Liberty is shaking/vibrating intensely starting around 45mph and gets worse right at 50 and over. Lets up a bit when you push on the gas pedal, and worse when you let off. Just had the front CV axles and front/back driveshafts replaced as all were very worn. I think the issue was there before the work was done, but only noticed it once on the way to the mechanic for the repair, as I hadn’t been driving it for a few months prior due to waiting on having the repair done. Folks at the repair shop drove it after and couldn’t pinpoint the issue. Plan to take it for another opinion at a different shop next week. Any ideas appreciated though!

This poor old girl has worn paint, rough interior, and needs a thorough cleaning.

100k miles, decent tires, no dash lights, clean title, second owner, and is a daily driver. We've done all the regular oil changes, belts, mechanical fixes, etc., over the years.

Anyone have a clue what she's worth? Carmax says $1500.

I have a 2012 Jeep Liberty sport. Started making a helicopter noise when turning and now it's all the time, sounds like front right wheel bearing. But I also noticed my front diff cover is seeping oil, not dripping. I don't feel any wobble in the wheel bearing when I jacked up that side. Maybe a front diff seal? Idk, I'm taking it in for what I think is a wheel bearing on Monday. Noise is the worst around 35mph and definitely changes when turning.

2007 liberty. I have a light pinging on acceleration when the engine is warm. It doesn't last long only the first couple of seconds.

I started running ethanol free gas as ran seaform through, then I put in double irridium spark plugs...no noticeable change.

That leaves timing, but before I start on that I wanted to see if I might be missing something else.

I’m planning on driving my 2005 Jeep Liberty up the coast this summer, beginning in Florida, ending in Quebec, Canada, and then back down to Florida. Total of 12 stops. Should be a total of 3700 miles or 62 hours of drive time. What should I prepare for and inspect on the Liberty before going? What should I bring with me?

This sucks 2 weeks our jeep started missing we'll it was throwing misfire codes for cylinder 2 so I changed simple the like plugs and coil pack an still misfiring so I figured it was a fuel injector so I wasted more money on that shit so I finally checked the compression an it only had 25 pounds lol idk why I didn't check that first before I wasted money but it has been a dependable vehicle we've had it since 2017 an it's got 308,000 miles so I reckon it was due to blow up lol anyhow this sucks bad so Don't do like I did and go replacing parts Go ahead and check that compression in whichever cylinder is misfiring to make sure it's got good compression lol

Any thoughts on what I should be looking for? It was my mom's, and has 147,000 miles. She says the main issues she's having are the catalytic converter is bad (or o2 sensors...) and of course she had the TIPM issue a few years back and did some sort of bypass on it to make it run. Otherwise she says it's a strong runner and doesn't have any other issues. Also, does anyone have any experience with the Infinity Gold sound system? Is it worth anything or should I take it out and install my own? Ice heard they sound okay, but I'm a little picky about my sound quality. Thanks for reading and any feedback!

I've had 2 mechanics tell me my front right CV axle and ball joint still need replaced but I haven't gotten around to those yet... I personally didn't trust either mechanic at the time because they seemed to be upselling me parts rather than fixing the issue I brought my car in for.

Hello everyone, I need help with my 2007 Jeep Liberty 3.7L V6. I have been dealing with a very frustrating intermittent issue for a long time and I’m running out of ideas.

Current codes:

P0174 (System Too Lean Bank 2)

P0300 (Random/Multiple Cylinder Misfire)

Sometimes P0138, then it switches to P0158

Previously had injector and ignition related issues

Main symptoms:

The engine shakes heavily at idle

The vehicle runs rough and unstable

I believe the issue is mainly affecting cylinders 2, 4, and 6

Power delivery feels inconsistent and the idle is not smooth

What I already did:

Replaced all injector connectors with new copper wire pigtails

Soldered and heat-shrinked every connection properly

Checked injector positive voltage (around 14.1–14.3V)

Verified injector pulse on all injectors

Replaced the PCM once

Replaced the EGR valve

Fuel pressure is around 50 PSI

Checked wiring continuity

Performed smoke tests looking for vacuum leaks

Checked upstream and downstream O2 sensors

What I noticed:

Cylinders 2, 4, and 6 behave differently from 1, 3, and 5

Injector ground pulse appears weaker on one bank

Sometimes disconnecting cylinder 2 or 4 barely changes the idle

The problem seems to move between Bank 1 and Bank 2 related codes

Could a bad ground, PCM control issue, shared sensor signal, damaged harness, or another hidden electrical issue cause this behavior even after replacing connectors and checking the wiring?

Any advice or ideas would be greatly appreciated. Thank you.
