- This is a Chrysler 300 that has some issues, one of which was a poor running, misfiring, and stalling engine. it has a 3.5 v6. normally with misfires it is a good idea to check the spark plugs and go from there.
In this case the plugs were very bad and were causing misfires to occur.
hopefully this video will help you out!
thanks for watching! please like, comment, and subscribe!
Like the video bro I just got 2007 5.7 charger I have 10 codes An this is one of them do you think I should change all the coils An plugs cuz it came as multiple misfires an I know the person had some bad wiring I think as well cuz I see electric tape on wires
Appreciate the comment bro!! I definitely recommend spark plugs. As for the coil packs, I replace those individually as they fail. Usually they will only set a code for certain cylinders so they are easier to diag. Clear your codes, and see which ones come back, then fix them as they set. Good luck with getting it fixed bro! You can lmk what codes come back if you’d like. 💯💯🤝
@@colin7761 ok so what about wiring wise I have a 2010 charger as well think I could replace them to the 07
Good video bro... question what kind of 02 sensors do you use. Seem like I have to change mine every few months
Thanks for the comment bro!! 💯💯 I haven’t had much issues with the o2 sensors. Have to replace them here and there but they have been good since. Bosch, Denso, and NTK sensors should work good! 💯💯🤝
@@colin7761 appreciate it bro 💪🏾💯
Question isn’t that a v6 why does it say the top speed is 220?
Hey bro!! Yes, it is a v6. The speedo shows that number, but it won’t be able to go that fast as it is limited to about 190 km/hr or 120 MPH. 💯🤝
Yo I have a scatpack with p0300 dealer said I need my heads replaced so I just got it back and it still doing same thing the same code came up yesterday now I have to go back to the dealership I’m also tuned some ppl say it’s the tune. But there’s no way I waited a month to get it back and still the same problem loss of power rpm not shifting on time
Did they replace the heads bro? Thats not right if you paid em to fix it and they didn’t even diagnose it properly or verify it was fixed!! It needs a compression test so you can see if it’s losing compression. If compression is good then we need to figure out why it’s not firing properly. If loss of compression is found then a leak down test should be performed to check whats going on. Good luck bro, hopefully you’re able to figure out whats going on. 💯💯🤝
@@colin7761that’s what I’m sayin bro I’m goin up there on bs today lol preciate u💯💪🏾
Hope you don’t have to deal with too much stress over this bro. Appreciate you too 💯💯🤝
I changed my spark plugs and coils and the misfire went away for 2 weeks then came back. Any suggestions? I have 2 misfires.
Is there any oil getting into the coils?
@@colin7761mines has
Change fuel injectors, easy, anyone can do it just takes a little time away from your regular life, Lol
Mine has this code but i just replaced the spark plugs a couple months ago. I may try the coil packs. What do you think?
Is this the only code it has?
@@colin7761 no it also has P0430, 0132, 0151, 0152, 0158,
Oh okay bro, have you cleared the code and this one came back? Do you feel it misfiring? Does the check engine light ever flash?
@@colin7761 ill have to see if it flashes i havent noticed that. i did clear the codes and some came back. the engine has shook and died not long after start up. Today its running just fine. I did get o2 spacers I am going to put on because of the cat and o2 codes. egr valve was recently replaced and no codes for that, it was prior to these other codes. Ill have to pay attention and get you more info.
@@colin7761 Youll never guess what it was. The pulley tensioner assembly was cracked causing the belt to slip and making the engine run like garbage. Replaced it and its running fine now. Cleared all the codes off with obd2.
Hello? I have a 2007 Chrysler 300 and it was misfiring. So, we changed the sparkplugs and the coils and new gasket for the intake manifold. Its drives smoother, but it still drives a little rough only when accelerating. What do you think it could be??
Does it have any trouble codes? Is it shaking or vibrating?
Check the throttle body maybe is dirty cleaning it with a specified soray
@@colin7761 No shaking, No vibrating and No engine light. I couldn’t take it to Auto Zone bcz there is no engine light.
No codes still? How has it been running? Do you have a scanner that monitors misfires in real time?
@@colin7761 I plan to take it to a nearby gas station mechanic. Hopefully he’ll find the solution but thank you.
Would this cause lack in acceleration?
Yes it will cause that symptom bro! 💯💯🤝
There are many reasons like not enough gas injected a very bad spark plugs also a bad coil etc etc first scan your computer for any codes
I got 5.7 and one of my coils had oil in it
Sounds like it’s leaking from the valve cover bro!! 💯🤝
