Question about Cars & Trucks
Posted by Anonymous on
Got the same truck and the same problem. It did it today and quit after i restarted it. The engine light symbol was on, and after i wiggled it i noticed it wasn't on anymore? Did you replace the whole wiring harness, or just repair (recrimp or resolder) the wires in the plug?

The following is a post from another site. I had the same problem and this worked for me.
I just wanted to share with everyone with the problem that I had withmy 2003 1500HD Crew Cab with 6.0 Liter. My truck would go into reducedengine power off and on. Sometimes one a week, sometimes 5 times on a20 mile trip. My problem was a broken wire on the plug in going in tothe throttle body. In the picture is the plug in that had caused me allof my pain and grief....... My problem was very intermittent and washard to diagnose. I started vehicle and with all codes clear. I wiggledthe wiring harness in the picture and vehicle spit and sputtered,throwing it into reduced engine power mode, and then smoothed out to asmooth idle. I disconnected the plug and pulled wires out of plug endand found a broken wire. Mine was a brown wire with white stripe. BUT,what was interesting, was that this vehicle had apparently had the smaeproblem with previous owner, becuz there was another wire (yellow wire)right beside the one that I found broken already soldered up and tapedfrom where it had apparently happened before. This was my problem andnot my truck is running great, and actually even idles better thatbefore. Hope this helps with any problems that anyone else is having. Iknow this problem can be very irritating.

SOURCE: reduced power for real!!!!
I had the same thing happen to me yesterday. Sitting at a light, went to accellerate and would barely move. The same lights came on for me too. I had it towed to the Saturn dealership and they tell me it's the computer control for the transmission. It's going to cost me in excess of $950.00 to replace. I did a little research and apparently this is an ogoing problem with 2003 Vues.
