Hi I am looking for some help to figure out what is wrong with my truck. It's a 2003 ram 3500 4x4, with 210,000 miles. The motor had a dead cylinder and the block was replaced at 205,000 and also 4 of the injectors were replaced. The truck has a airdog fuel system banks intake manifold and a diablo sport predator programmer. I've had for about 3 months with no problems until today. It is hard to start and idles a little rough surging from about 600-800 rpm and also sometimes starts and then dies right away within 5 seconds. Also when I am driving and coming to a stop the truck will stall. This is my only vehicle that I have to drive and I cant afford to have it break down on me any help would be greatly appreciated thanks.
