I have a 2003 Esclade that has an intermittent problem. During the fall and spring we will be driving and all of a sudden we get an error message that says "reduced engine power *** traction disabled" The vehicle slows and will not go faster than about 25 mph. If we pull over and shut it off the problem goes away. Lately, it has been happening more frequently; as much as 4-5 times during a 20-30 mile trip.

We have taken the vehicle to the dealer and they cleaned some sort of cord on the throttle body. Does anyone know what might be causing this problem?

Quite an annoying problem that could be dangerous also! I think I've seen this error message covered in the owners manual. Have a look and post back.

Jeller,
I have an 05 Cadillac Escalde 6.0
I just had the same problem and brought it to a cadillac specialist in Atlanta. It was a bad throttle body. they are electrical now. It was $450 for parts and labor. I am a liitle concerned about the repair because it has done it once since the replacment. we will see what happens now

Thanks
EJ
