I have an 01 dodge ram 1500 5.9v8. Struggles to turn on and I have to give it gas to keep it idle for about a minute if u don't it struggles to stay on and looks as if my dashboard is dimming in and out with the idle as it truss to stay on plz help.
Sounds like the battery might have been disconnected or run dead recently. If so, the Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
