HI - new to the forum and have seen some related threads with some of my symptoms or all of them but for the SRT so the fix might be different. I have a NA 2008 Crossfire with about 30k on the clock.
Car runs well from the start but i am sure it should be quicker than it is. However, as long as I don't stop and air is running over the engine its fine. If I park up to go shopping - 15/20 minutes later its running rough, stalling, engine light on for a few days - once its cooled down back to normal. Whenever I get fuel bonnet (hood) up so the heat doesn't build up and so far so good. In stop start traffic you can see the temp rise and the engine starts to get lumpy and can stall. When I first noticed the problem (like you can miss it) I did a quick search on the net and the crank position sensor was mentioned so I changed that. Didn't make a blind bit of difference. I then did more research and found that I could in fact embark on replacing every piece of my engine and still not solve this problem. Its definately related to heat and the nearest thing I have found that matches what I am experiencing in heat soak. Any help out there?
