Ok, So I have been checking all my hoses today, I have found nothing loose or disconnected or anything. So what do I need to do next? There are 4 O2 sensor's on this thing, so do I start buying one and replace them one at a time till I find the one thats bad? What would be my next step... I'm open to suggestions. Thanks!

 

Replacing all O2 sensor gets expensive, they are like $80 each, no? And i do not recommend Aftermarket O2 sensor. They work, but OEM gives more gurantee. I don't think Throwing in $300 worth of stuff in and 1 day worth of work, and Hoping to fix the problem is a good idea. And if the O2 is the problem, rough running should occur all the time, not just idle.
Hitting the dealership for Diagnose could be cheaper and easier.

I think You have a Vacuum leak, when u turn on A/C, the engine takes more air and fuel, which use up the Air from the Vacuum leak.
Take a Bottle of Brake cleaner and spray around intake manifold, see if any change to idle quality. mainly where Hose joins the Intake manifold, as well as Sealing surface area.
use Plier to Pinch off each hose one at a time, see if any hose u pinch off changes idle quality. Especially PCV hose. If PCV valve stuck open, u get a internal Vacuum leak.

 

Compression test. Also have seen the intake gaskets rot out on some

 

Ok, tomorrow I am going to to try and find a leak somewhere, Ill keep u posted. Thanks for all the help, we will see how things work out.

 

Ok, i replaced 2 of the coils in the charger to not avail. everything seems to be running the same as before, now i have more codes popping up. guy at the parts store told me it could be my MAP sensor, what do y'all think of that? I hate to keep buying more coils if this is not the problem at 42$ each. What do you suggest?
Thanks

 

what's the codes?

why did you buy coils? what are the Chance of all coils needs to be replaced at once? (unless u have a Nissan)
If you just keep throwing parts on that recommended by ur "part store guy", you better off just pay the dealership $100 for a diagnose.
Is the Code is for MAP sensor? Check the seal around the MAP sensor.

 

After doing extensive research.. this is what I did.
1. I cleared all codes on the car.
2. cranked up the car, checked the "new" codes.. code I got was P0301, which is cylinder 1 misfire. Today I replaced the coil and plug on cylinder 1 so this is what 2 options I think are left for that cylinder, #1 replace the EGR valve, or the Injector is not working on that cylinder.

So what do y'all think? I have to order the EGR valve so it will be a few days before I get it.

 

Maybe the injector, but definitely not the EGR valve.
I think Autozone rents compression gauge, do a Compression test on that cyln, and compare it with the others.
Maybe u got a Mechanical problem like TNtech mentioned b4.

 

Jeffa82, any updates? I have the same problem with my 2007 Chrysler 300, 3.5L V6. My CEL had went on and off several times over the course of a few weeks. This past week, it went on, stayed on, and started idling rough. Had the codes pulled, only p0301 (cylinder 1 misfire) was registered. Figured I just needed a tune up (72,000 miles), so I replaced my plugs (cyl 1 plug was fouled out compared to the other 5). I also switched coil 1 with coil 2 just to make sure that coil 1 wasn't bad (plus I wouldn't have to remove the intake to get to coil 2).
Took the car for a test drive, within 15 minutes, CEL tripped. Pulled the code thinking it would be a misfire in cylinder 2, indicating a bad coil, but to my surprise, it was still p0301.
Before tearing everything apart again, I thought maybe I had bad fuel or a dirty injector, so I ran lucas injector cleaner plus a bottle of Heet through my fuel system. Been driving it for 3 days now and it's gradually getting worse. I can now feel it misfire at pretty much any speed, however when I accelerate, the misfire seems to ease up.
Any thoughts would be appreciated!
