Hello all
I have Chrysler 300 2013, 3.6 V6 engine with 100.000 miles.
The first issues:
When turning around a circle or roundabouts, steering wheel tends to resist ( it gets harder to turn) in increments, it's like power steering on and off feeling. Fluid is fine, belt is new.
The second Issue:
Check engine ON , scan tool is throwing P0305: detecting misfire on cylinder #5
I changed the coil pack and spark plug, cleared the fault code then it popped the same code.
I am thinking of replacing the fuel injector number 5
My questions:
1. If the code is triggered by the injector, wouldn't that trigger another code?
2. Having changed the coil and sparkplug is there any other possibilities aside from a bad fuel injector?
Thank you all

 

Hello there
Just an update to my earlier post with solutions, perhaps someone out there may face similar problems:

1. The power steering fluid was at 1/2, topped it off , problem solved. It is an electrical pump hidden in the wheel well on passenger side.
2. The misfire on cylinder number 5 was due to dirty fuel injector, replaced one and removed the other 5 injectors, cleaned them, problem solved.
see attached picture.


This is Number 5

 

Now you should ask yourself "where did that Power Steering fluid go to ?" You got more trouble lurking.

Could you describe how you cleaned the injectors ?

 

Well, I used these:
1. one bottle of STP fluid injector cleaner, poured it into a small container and soaked injectors for about 15 minutes.
2. one can of Liqui moly throttle body (TB) cleaner.
3. 9 Volts battery and 2 small wires to power-on each injector, this opens the injector. Also when you power injector by the battery, you should hear clicking/ticking sound, which means your injector is working ( kind of testing)
4. several layers of electrical tape wrapped around the straw so the can's straw seals inside the opening on the injector.
5. Pressing several shots into the injector till clear fluid comes out of the other end of injector.
You will notice the difference, the first 1-2 shots = dripping brownish gummy substance, after 4-5 shots = free flow and clear fluid.

Note:
The Chrysler dealer in this country wanted to charge 950 in their local currency = $254 for one injector.
Ordered one Mopar injector from Amazon for $75.92 plus $38 shipping.

I hope the above helps and answers your questions, stay safe!

 

Many thanks Joe. You are a gentleman to respond.

 

Good work. Just curious, what country are you in? I notice all the find brown dust on everything. I'm a bus dealer and we had a couple used buses come in trade that were just full of dust and sand. We never figured it out, but after cleaning things up all was fine.

 

Hello Captain and thanks for the compliment.
yes, you are right, I am in Saudi Arabia and that is the sand storm I shipped the Chrysler from NJ.
In fact, I wish to update you with the solution to misfiring in this thread with the hope no one will ever go through it.
It turned out to be the rocker arms on Cylinder 5.
This problem is well documented all over the internet with a simple Google search (3.6L Pentastar Engine TICK TICK TICK ) however my car did not make any ticking sounds which threw me off, really. After cleaning injectors, thinking problem solved check engine light came on again.
So took it to the only ONE Chrysler dealer in Riyadh, the capital and I did ask them to change all 24 rocker arms and lifters, I just hope Chrysler did some kind of an upgrade to the old parts because the stock rocker arms definitely defected by whoever manufactured it. Add to it Chrysler has been pulling this dirty game by saying (oh well, we will honor and replace cylinder heads on bank 2 only) The misfire I had was on Cylinder 5 which is bank 1, with no coverage, convenient? Nah cute isn't it?
Anyhow, the car runs good and no check engine EXCEPT a constant drop in RPM. I am thinking vacuum leak? or worse the catalyst converter?
I guess I'll post the specifics on that to get some feedback from you guys and hope it is some minor leak.
Take care and stay safe!

 

Having split the upper and lower plenums, it would’ve been the opportunity to replace their gaskets when changing the plugs your first go round. Although they’re not mean to be done every time the plugs are, they’re inexpensive enough to do anyways, especially if saving you the headache of a vacuum leak.

 

“I changed the coil pack and spark plug, cleared the fault code then it popped the same code.

im sorta having the same issue but mine is cylinder 4 i swapped the coil spark plug and fuel injector and i’m still getting a misfire also i don’t get a misfire code either

 

Experiencing power steering issues while turning could be related to various factors, even if the fluid and belt are in good condition. Here are a few things you might want to consider:
Power Steering Pump: While the fluid might be at the correct level, the power steering pump could still be struggling or failing intermittently. This could lead to the on-off feeling you're experiencing. As with online casinos, if the project is good, the support will respond quickly, for example, there is information about https://casinosanalyzer.com/online-c...opian-birr-etb one such casino. Steering Rack/Column Issues: There could be problems with the steering rack or the steering column that are causing the resistance you feel. These components may need inspection by a mechanic to identify any wear or damage.
Electrical Issues: Modern vehicles often use electric power steering (EPS) systems. If there's an issue with the electrical components, such as sensors or the EPS control module, it could lead to intermittent power steering problems.
