In this video we take a look at a Jeep Liberty 3.7 that was purchased from an auction and then towed into the shop from a local dealer. You could get the engine to start on occasion but when you did it had a lot of mechanical engine noise and would not idle. Let's see what we find. -Enjoy!

I've always had good luck with ac Delco.
"Ngk spark plugs are junk!"
My 2008 jeep liberty. Will start no problem after running it and turning it off it wont start up with pushing the gas also while driving after that I notice its feeling like I'm running out of fuel and wants to stall..please help
Illlll
Great stuff
Oh, NGK spark plugs are junk. And yes, that is how I sound.
Who says NGKs are junk? Champion on the other hand…
Love your break down on your diagnostic thinking, its like a master class of a who done it for engines. My only wish would be to see a properly working cylinder go through its paces to show a comparison. I guess I could imagine what it would be but the thought went through my brain when I saw the one with the sticking exhaust valve. Love your video's , I honestly think your prescribe to the Kiss method, you take a complex situation and break it down so dumb guys like myself can catch up to your thinking. Thank you. It gives me hope that some day because you can do it, so could I.
Is that's why your thrateal (sp) is messed up because of back pressure ?
Have an 05 jeep grand Cherokee 3.7 has random misfire code and a n/a . Changed all coils ,plugs ,and injectors. What's next burn it?
This is the 12th South main auto repair video I've watched recently and I'm 12 for 12 on the diag, quite chuffed 😁
everyone on 3,2,1…..jeep wave 👋wave 👋
I know this is a older video, and my question might not have anything to do with this video .. and not sure if i had asked before. But here goes .. Ever do a engine swap, from a 2005 3.7 L liberty to a 2004 Liberty Limited >? Im getting ready to do that, see my 05 lib frame broke and its a none repair. so pulling the motor out and putting it in a 2004 lib limited .. I have heard i will have to change out the Cam gear sprocket due to timing issue`s or i would have to swap brains.. How true is this, being how both motors are 3.7L . being how they are both 3.7L same engines. i am hoping it a easy swap over and not have to doing anything in the way of opening up the top end, or change the brains out … Any advice
Have a 2004 liberty 3.7 I’ve been trying to fix . My whole passenger side is misfiring . I changed coils , fuel injector seals , o2s and spark plugs . Only codes I’m getting is sensor 2 bank 1 voltage high and multiple cylinder misfire . Do you think changing the crank and camshaft will fix it ?
Still runs great. I know, because it's my jeep 😅
Eric why haven’t you done anything on the Jeep fuel pump relay recall?
For 20 bucks could have replaced the TPS and been done
car got flat tire lol
2007 liberty starts but stalls when put in gear ???
(
It's the choke
Sounds familiar. 12 years ago, while 8 degrees outside, my 4.7L Ram 1500 started overheating after 1 mile from being started. As soon as I pulled over, the coolant expanded enough to reach the pump and the temp came down immediately. Added coolant and made several stop and start drives over several hours. When I got home, I parked it in the road as someone was in my driveway. Later, I went to move it to the driveway and it was running horribly and making popping sounds in the manifold. Compression check was showing strange results on the left side. Pulled the cover and an exhaust rocker arm had fallen off. Popped it back in with a wrench. I'm not sure why it only became a problem after several drive cycles but it's been 12 years and I've never had a problem since. The root cause of the problems was a cracked radiator caused by a bad overflow cap causing too much pressure for the plastic radiator sides to handle. The radiator hoses blown up like balloons helped with the diagnosis.
Starts stalls runs like poo crappy design ,who ever bought it jokes on you.👄👄👄
How many times have you selected "Ferrari" on the scan tool?
Fascinating video!
Cool cant wait to see the conclusion
I have the same problem with mi jeep . Thanks a lot for this video very helpful.
If you also put a pressure transducer in the intake manifold, you can learn more about valve problems by viewing the intake manifold pressures and vacuums.
Wow, this makes me look at the mechanics of an engine in a new light!! Awesome!!
Sounds like something cross a on injector or a coil pack wire
And NGK makes the best spark plugs on the planet thats why the Asians only use NGK !
NOT A JEEP AT ALL ITS FIAT JUNK !WHAT DOES A FAILING COMPANY DO TO SURVIVE IT BUYS ANOTHER FAILING COMPANY TO BUILD SUPER JUNK ! SMH
Maybe the owner should have changed the oil as opposed to polishing the engine bay.
being a chrysler, maybe needs a ecm
i live in Wisconsin, alot of stupid people
Oh NGK sparkplugs they are boring
My '88 Jeep Cherokee came with Champion spark plugs. One piece of advice I've gotten concerning spark plugs is, if it didn't come on the car from the factory, don't use it.
I know this comment is old and probably won’t get be seen by anyone but couldn’t you just take the spark plug out of one of the cylinders you think the exhaust is stuck on (giving the exhaust a path out) and then re-run relative compression and see if you amp draw on the high cylinders goes down? Obviously the in cylinder test is more definitive but this seems like it would work for someone that doesn’t have a pressure transducer.
Wow
Sounds good to me, nothing wrong.
Just Empty Every Pocket 😂
This guys is good stuff. Acutally uses the scientific method! What a great dude! Bet he doesn't wear a mask because he has a brain.
So exhaust is going into the intake manifold back out the intake valve?
“Like jeeps sometimes do!” LOL. You are not kidding. Thank you so much for your videos. This was great information regarding firing order, exhaust, and compression. I like to understand how it works. Working on my daughters 07 Commander with 202k miles. It has the 3.7 like this liberty in the video. Nice addition to my Jeep videos.
This is what a very skilled mechanic looks like these days – fantastic work and teaching Eric !
Wham Bam 💥 Bino!!!!
