I had a 1999 Dakota V6, 5 speed. My family used the thing to blow up air mattresses (12v plug in blower). They did not start the truck up first. I went to go start it, and it would not start at first. After a bit, it would start, But it would not idle. I was able to get it back to the dealer (warranty), and they said that the Idle Motor had been damaged by the low battery voltage. They replaced the battery and the motor under warranty (God I miss Good dealers). Mebbe you are right. Mebbe the ideal motor is on the edge.
