Having problems with your 2001 GMC Yukon ?
REDUCE ENGINE SPEED
\015 WHILE DRIVING A CERTAIN DISTANCE THE REDUCE ENGINE FLASH ON MY MESSAGE BOARD AND WONT LET ME DRIVE PAST 35 OR 40 MPH\015
There is something going on with the electrical system. I think it would be best to take it into a shop and pay $30 for an OBD2 diagnostics. There are far to many things that could be causing it and to replace them one by one could end up costing thousands of dollars. Best to have the diagnostic computer tell you what the problem is.
