I have a 04 dodge 1500 with a 5.7. Two days ago after driving it over to a friends house it would not start. After trying it for about ten min., it finally started. But all it would do i idle. luckly i was only a mile from home and idle home with it. It had a code of p0340 camshaft sensor. so i replaced it. still no throttle response. and hard to start. i checked the codes aging and the camshaft sensor code was still there. I did replace my egr valvue about two weeks ago. does anyone have any advice on where to start know
