mobowhunter 12-03-2003, 03:22 PM Had this happen about 30 minutes ago. Driving down the road at between 1800 - 2000 RPM's, and the truck acted like it was stalled, lost power, didn't die, backed off and droped down to 45 mph then started picking back up. Any thoughts???? GMC-2002-Dmax 12-03-2003, 03:39 PM Had this happen about 30 minutes ago.

As I was coming home tonight same thing happened, then through a P0234 DTC (Engine Over boost Condition). I went ahead and restored stock programing just to see if it happens again. My first thoughts was bad fuel, Fuel Filter only has 28 hours on it. I am leaning toward the programer, This happened on the Tow Safe mode, +55. turbodiesel03 12-04-2003, 11:12 AM MINE DID THE SAME AFTER INSTALLED THE JUICE BOX.....I WAS TURNING INFRONT OF TRAFFIC AND ALMOST GOT ME KILLED.....THE BOX WAS NOT MAKING A GOOD CONNECTION....UNPLUGGED AND PLUGGED BACK IN AND NO PROBLEM...... | ||
