I have a 2008 Chrysler crossfire and the screen modular had went out in it send it back to a company on the East Coast got it back and when I got it back it would start but now I have issues with it starting all the time and it doesn't run as good as it did replace all the spark plugs replace the cam sensor replace the different things on it the starter replaces starter and still don't know I'll let and the codes the only codes I get is it's a random misfire so it's very frustrating not too sure what to do almost wish I wouldn't have sent my screen modular to the company because it ran really good before I did that and now it just runs okay. Sometimes it'll start right away and other times I have to put the key into the the chi area turn it to the ACC that it sit there for about 5 to 10 seconds and then turn it and it'll start but sometimes it takes like five or six times turning the key before it starts does anybody know what could be going on with this car
