My truck was dead this morning. After I jumped it, it would start but as soon as I took my foot off of the accelerator it would die. I could keep starting it, but it would die every time I took my foot off of the accelerator. Could it be the battery or do I have another issue?
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.
