Thanks but it was not a runaway diesel, idling did not go through the roof. Instead it was stabilizing 200-300 rpm's high. Over the first 35 miles it called for some interesting shifting techniques with the 4-spd, thats for sure. And now the problem doesnt exist at all. Am wondering if fuel separation is possible where more flamable stuff drifted to bottom of the tank over 6 weeks of standing still.
