Hey everybody! I got a 1998 Ram Sport with a 360 about three weeks ago. Ive noticed that after the truck sits for about an hour, it will idle really rough when I start it and it will feel really down on power and it will also backfire if I give it any gas. The problem goes away after like 15 seconds, but I have no idea what could be causing it. After it goes away it won't come back until after it sits for a while. Any help would be greatly appreciated!
