Nice. I just replaced the Coil on my Cylinder one. 2012 3.6 vvt. Took less than 20 minutes and $43.60. No more shaking every other day. Yay.
Nice good job!!
The 3.6 and 3.8 Jeep are my babies. Gotta watch for roller rockets on the the 3.6 with misfires. 🙄👍🏻. A little silicone spray on the purge valve bracket and air intake studs makes it much easier
I changed all the coils and plugs hoping that was the problem but I think it’s the roller rocker cause the misfire didn’t clear.
@@Ewandabbles probably the problem. Maybe you will get lucky and cam will be salvageable. And only need rockers
Thanks for the video. I don't like turning wrenches anymore but I can't justify paying someone for the easier tasks
Welcome!!
I had really nisgires on multiple cylinders on GC 2020 plus o2 sensor and start stop warnings. New Map sensor no dif. Bank 1/2 o2 no dif, bank 2/2 stopped it but it also replaced start stop battery and flushed pcb memory. So far do good.
Great video
Thank you
great video but this is different for the 2017 pentastar you have to remove the intake and its a lot of work .
Ok
Got a 2010 3.7 misfire on 3 and then got a multiple misfire. Bought new packs 6 months ago, new wires. Haven't check plugs but we're new less than 5,000 miles ago..hoping not internal..
Did u check spark plugs and vaccum leaks
@@RBTheMechanic bought the jeep about a year ago, 2 weeks later very rough idle misfire on #6, went through all the videos replaced the coil packs, wires plugs were new.
End was blown head gasket..fixed and ran fine since October of last year..
Now 2 weeks ago we had a severe storm with major flooding..drove it through deep water on my street up to the bottom of the door and noticed it running rough once out of the water..couple miles later ran ok...did the twice through the water.
Now, last Sunday went to car wash and as soon as the water came around the jeep started shaking again but was different so I checked the code and got the 0303, and the next day a 0300..going to check the plugs and switch a coil pack today.
Just pulled the coil on #3 and has gas all over the bottom.
Just did jeep wrangler for mis fire #2 cylinder found cracked exhaust valve!
On a 2017 the engine is a mirror image, 2,4 6 are in the open and 1,3,5 are under the intake. Naturally I have the problem under the intake 😒
Oh ok
Thaks for this video!
Welcome
The wiring harness can also burn out, on the end closest to PCM. Unplug look at the clip it will be burnt to a crisp. Harness will need replacing.
True just like headlight connectors taking bearing from heat
I have a 2019 missfre cyl 3 we changed the coil spark plugs still same issue when u do full gas it starts shaking check engine pips then goes away sometimes it stays for a little
Any ideas?
Ok so I would double check to confirm if u did tackle the coil on cylinder number 3 cuz these are bit confusing to pin point which one is cylinder 3 other wise swap the coil to diffrent cylinder and it’s possible to have bad injector on these and check Paulse in injector and coin anways try basics
@@RBTheMechanic we did make sure that we did it right also he thinks it might be the injector thats doing that what do you think
@hasan did you figure out the problem my jeep is doing the same thing waste almost 1k already fixing it and still the same problem I took it to the mechanic again yesterday and they said it can be the engine dying I have a 2018 jeep grand Cherokee 65,000 miles
@@diegoaucancela7813 this was the issue bad coil
I have a P301 Cylinders misfire & P0201 Fuel Injector 1 circuit/open.
The mechanic told me to buy 1 fuel injectors & 1 set up intake manifold gasket. Why no cylinders?
For my 2016 Jeep Cherokee Limited 3.2,
I plan on buying 6 fuel injectors.
I'm having problems buying the correct fuel injectors from RockAuto. Is part Mopar 2627794AA good? Thanks!
Ps: I already bought the Manifold gasket kit, spark plugs, air filter at Auto Zone.
There are still codes
P1C86-D (PRNDL display - circuit out of range)
U1465-00 (Implausible driver shift request signal received)
C14A7-97 (PTU Motor - component/system obstructed or blocked)
I don't know what to do about those codes. Thanks for any help.
Put in original injector after markets be defective lame parts
@RBTheMechanic
Thanks. I'm planning on buying Mopar fuel injectors.
@@urpreposterous682 ok good
I had to change the whole engine and transmission and catalytic converter and it's still throwing miss fired from 3,5,4. I have 2011 jeep grand cherokee limited
Did u replace oxygen sensor for that bank
Check the PCM harness connectors to the module and make sure you don't have any bent pins or misalignment in either connector to PCM! it's very easy to get those connectors plugged in wrong... just a thought!
@@RBTheMechanic I think they said they did. I'm have to double check I'll get back with u
@@patrickbennett6010 thanks I will add that to the list
I have a 2015 grand Cherokee Laredo with P0303 I have changed coil and spark plug. There’s good compression, injector is good, swapped coils and I’m still getting same cylinder 3 misfire. Any help please sad😢
How did u check the injector and I would swap the coils and plug again to diffrent cylinder check the connector on coil. Anyways u can see live misfire data
did you figure it out?
Is the cylinder lineup the same for a 2017 3.6L Durango ?
Oh yes same
What if you see oil on the coil/spark plug?
Then u need to replace valve cover and gromet gaskets
@@RBTheMechanic thanks, but could that oil on the coil/plug cause a long crank before starting?
How much would you charge for this fix?
To take out the intake is like 290 labor
So why didn't you start the Jeep to prove your fix ? Replacing parts and fixing are two different things. I hope you are correct. Te Jeep dealer here in Costa Mesa,Ca. has no clue ! They demand $ 1800.00 to do a tear down because they don't know what to do.
Well it was fixed I guess next time I have to show before and after. But it’s been good every since. U just got to go by the code
@@RBTheMechanic My daughter has a similar problem and the dealership is charging her $ 1800.00 for a tear down. She has a lifetime warranty form jeep that she paid
$ 6,000 for
@@terrymogis6435 they crazy I would argue with this they might not cover this because it’s not power train components but the coils is $68 and spark plugs $120 labor at ur local mechanic no more that $300
@@RBTheMechanic Update ! Thank you for your input. They finally found the problem ,it was cylinder # 1 and they are replacing the cylinder head. $ 4300.00 for the replacement and the insurance will cover the cost. This jeep grand cherokee has 43,000 miles on it. Many repairs to a vehicle that was never abused and had exce;;ent care. This is why I would never purchase a Chrysler product. I can't trust their lack of reliability. I have had 4 tacomas and never experienced and problems with them. Thank you once again. Carry On !
Bro thanks for your help 🫡
No problem 👍
