Trying to get some ideas and information.

I have a 2007 Chrysler 300. 2.7 L. It turns off randomly. I feel like the colder it is outside, the worse it is. I start it everyday fifteen to twenty minutes before I have to go anywhere to let it warm up. That helps. But its never 100%. I also feel that the rpms are low. It idles at 550-600. I've had it checked told it was fine. The battery was replaced this year as was the alternator. I can feel almost... (i want to equate it to bubbles in the exhaust maybe) underneath my feet, the car beginning to hesitate and the rpms drop rapidly. I come to a light to stop and it completely turns off. Like it loses power. No lights turn off. There is NO check engine light on and it is NOT throwing ANY codes! I dont notice a difference in the amount of gas I have in the car. I have even tried changing the gas I get! We've put cleaner in the gas tank. Sent some other cleaner through the system to see if there was carbon build up. Spark plugs have been changed. I feel like the problem isnt electric that whatever it is, has something to do with the gas. We're starting small and trying to work our way up because I dont want to continually sink money into this car blindfolded, although for the time being, it is the only one I have! Even changed the air filter today! Any and all help and suggestions are appreciated. Thank you for your time!

 

Might be a clogged fuel filter. BTW, 15-20 minutes of warming up just wastes gas. The car will warm up quicker and use less gas by driving it, not letting it idle in the driveway.

 

Have you checked IAC operation, or cleaned the throttle body???

 

U
yes i know... but if i don't, the car will most definitely cut off. The car has to be warm already for me not to have any problems.

 

yep! I have a mechanic that has done quite a few things and has just told me to drive it until the wheels fall off! Haha. Yeah he ran a spray through it of some sort for carbon build up on it, and ran the computer while driving it and everything is opening like it should. I've done so much research and have heard egr valve mentioned a lot..

 

Yes it does have an EGR valve and a bunch of tubing with it, a trouble prone area on all 2.7 equipped mopars. can stick open partially or even plug solid and the tubes rust out, for a short description of its "maladies" they can exhibit!
