Misfire and rough idle

Hey guys, I have a 2006 Charger SXT 3.5L HO and recently I have gotten a code for Cylinder 5 misfire (P0305) and now it is starting to idle kind of rough and even shake or shutter after I come to a stop at an intersection. I changed the spark plugs (#5 was more worn than the rest) and swapped coil pack 1 with 5 (since 1 is much easier to get to in case it was the issue). Well after the spark plug change and coil swap the misfire on cylinder 5 is still there, so I know it was not the spark plug or the coil pack. I have run fuel system cleaner several times recently and even tried premium fuel and it is still running rough and shaking at idle after I come to a stop. Sometimes I even hear a knocking noise with the shaking. I am thinking I am going to have to take it in and have it looked at since I have run out of ideas. Has anyone else had anything like this happen? and if so what was the cause? any information would be greatly appreciated, thanks!

Hey polarbear18w,

I had the exact same problem. I have the exact car as you (06 Charger SXT 3.5 H.O.) The car went to the shop 4 times. At first they cleaned the carbon out of the engine. Next they had to replace all of the Valve-springs (which is a recall on the 06 charger). The problem kept arising after each visit. Finally on the list (they know from the beginning) that an exhaust valve on that cylinder (code read by computer) is actually sticking. So what happens is the combustion happens in the cylinder, but the exhaust valve sticks and causes the car to shake violently and almost stall. After this repair was done, the car ran great. Another problem I have come across was the car running rough and shaking with a code on, which was actually the EGR valve. I bought the part for around $90 and replaced myself (need to reach way in there over the tranny). But the car is running great now, haven't had the problem come back in half a year already.

Hope that helps!


Rob

Thanks for the quick reply. At least there is hope, but it sounds expensive to replace the valve springs and exhuast valve. From all my searching, I had seen that it could be carbon buildup in that cylinder causing the exhaust valve to stick hence the shaking, and that a vacuum leak in the EGR could cause the car to run rough. Good to know that the EGR can be done easily, but I guess I will have to take it in and get cylinder 5 looked at before it gets any worse.

Thanks,

Paul

Good luck! I'm sure after the problems I had with mine that you will need to replace that exhaust valve. Seems to be a factory issue. After the engine gunk is cleaned out the car runs amazing though!

Was yours covered under warranty? how much should I expect it to cost? and what have you been able to do to keep it from happening again?

Mine was covered under power-train warranty. The car was in the shop for over a day because the engine needs to be torn apart to replace the valve. The EGR valve was not covered though. I think after you have the part changed, run your tank low and then fill up with premium gasoline to clean up the carbon, I found that helped a lot after I had it fixed. It's still running strong with no problems.

How many miles do you guys have on your cars? I have an 06 3.5L w/ 90K miles and have never had this problem...sounds scary tho. Do you guys use engine cleaners/ lubricants like zMax?

I only have 58k miles on my 06 3.5L. I have not heard of zMax but I do put fuel system cleaner in at every oil change (either Lucas Oil or Seafoam). It started last winter and I took it to a shop for the misfire and they treated it with Seafoam and that worked until recently it came back. They said it was carbon buildup in that cylinder causing the misfire.

Hey guys, quick update... So I took it to a shop that my friend recommended (the guy there has had Chargers and worked on them before) but he said he has never seen anything like this before. So then I took it to the shop I normally go to and they said that if it is the valve springs or exhaust valve that they would not do it. Looks like no one wants to work on this issue and I am going to have to take it to the dealership this week. Anyone else have any last ideas before I take it to the dealership? I am going to call the one by my work tomorrow to talk to someone about it.

Thanks,
Paul

Hey the Valve-Springs are an actual factory recall, so they will be covered under warranty. My car only had 40k miles when this was all changed. As for the Valve sticking it will also be covered under powertrain, as long as you still have warranty left!

Good luck,

Rob
