Anyway, I sat down and read the owners manual (as you do on a slow night on TV) and I noticed that Premium fuel is not recommended and to use 89octane on the 3.5 and 5.7 engines. After clearing around 3/4 of a tank I filled up with 89 and the rough idle seemed to have subsided quite a bit. After a few tanks of 89 with no body tremble whatsoever, I pulled into a station that only had 91 premium available - the rough idle returned almost immediately after I filled up. Definitely sticking to 89 oct when available. I still notice a bit of a rumble through the pedals, but don't get the trembling through the seat and car that used to happen. Performance doesn't seem to be affected using 89oct over 91oct either, and the car is smoother and quieter on acceleration and at speed.
This may not be your problem, but worked for me.
BTW - I haven't had any wiper problems (touch wood).
That's kinda funny. My Camaro does the same thing (I'll fix it soon - it already caused a blade airfoil to break). I'd be upset if a 300 did that...
Anyone having rough idling?? The dealership told me that it is the cam
I believe the dealer (for once) is actually correct. Seems that some cars do it more than others, but this pushrod V8 with no variable valve timing (and 340hp) isn't going to idle like a Lexus V8. That's just a fact of life.

Check my July 6 posting at the Edmunds 300M Forum for details, phone numbers, etc.
Things I like so far. 1. Sirius radio. I wouldn't have ordered it, but now am hooked. 2. Smooth ride 3. Acceleration at the on ramps 4. The older gentleman who tapped on the window to ask how we liked the car and to say that he was having trouble finding one. 5. No right pull. 6. The dark green color of the dash complements the light green exterior. 7. The fact that my older son, who doesn't like to drive much, drove for 3 hours straight and wanted to do more. 8. Seemed pretty quiet to me while cruising at 80, 9. nice sound it makes when asked to accelerate.
No complaints to date. :shades:
My 20 minuets in a C did not include highway. However when examining the handling on a twisty, I thought I was doing slightly more than 40, looked at the speedo, and found I was doing 60. No noise, and it felt like about 45. And it was immediately noticeable as being substantially quieter than the Audi A6 I was then driving. I'd describe it as a very quiet sedan.

Coming back at 2:00 a.m. on a Sunday morning I got stopped by the Quartzsite police for going 91.
Nobody on the road. The lesson here is to be careful and drive the same at 2:00 a.m. as 2:00 p.m.
By the way....the car is smooth at 120 and the zoomers exhaust rocks.
Seven months and 10 thousand miles....I'm very happy.
BTW--CAUTION--the salesman cautioned me against getting tire sidewall conditioner slopped on the plastic--that it will spot permanently.

If you run into this problem with your C then demand that they be replaced and don't take no for an answer.
Someone makes a manual available for Chrysler mechanics; if it's not offered in the back of you owner's manual, he can tell you who supplies them. It may be pricey. I think my last one for my 03 car cost $120. A CD was available that covered many GM cars; I opted not to get it. Now it's not offered at Helm.

I live in San Jose, my Grandson lives near Seal Beach.
I like the Navigation system. It is especially good when I take side trips after arriving to destination. It was easy to get back to my Son's home.
I also like the Sirius radio, especially channel 5, for the Golden Oldies. I liked to roll down the windows and turn up the music while in traffic. Great Boston Speakers.
The hands free Bluetooth worked good too especially in traffic.
The power going over the Grapevine Mountains was never questioned. It took the mountains with ease.
It was also cool that most everyone likes to check out the car. That is easy to understand. My polished Silver 300 C is quite a handsome looker.
I am going on a road trip next week. South FL to TN to NY then back. I'm renting a 300 for 7 days. Getting the limited/touring model from Dollar. Great deal at only $226. Have some questions...
This version has the 3.5L correct? If it does do I need to use midgrade gas? I know the 300M I had used it. How are the seats? Will I be comfortable in them for such a long drive. Do the head rests tilt? Does it have a CD changer or single cd? I rented the base version before, but not this upgraded one so I'm not sure what it has.
Thanks
