THERE IS AN ERROR MESSAGE THAT DISPLAYS ON THE DASH FOR MYSELF AND THOUSANDS OF OTHERS WHO OWN GMC/CHEVY TRUCKS WITH THESE MOTORS. THEY HAVE A DEFECTIVE THROTTLE POSITION SENSOR WITH THE TRUCK WHERE IT SAYS "REDUCED ENGINE POWER". I'VE FOUND 2 TECHNICAL SERVICE BULLETINS THAT SOMEWHAT ADDRESS THE ISSUE, BUT MANY PEOPLE TAKE THEIR TRUCKS TO MECHANICS AND DEALERSHIPS TO GET THE ISSUE FIXED AND SPEND THOUSANDS OF DOLLARS IN REPAIRS AND TROUBLESHOOTING TO GET THE ISSUE RESOLVED, TO NO AVAIL. THE 2 TECHNICAL SERVICE BULLETINS THAT I FOUND WERE #PIP3089B (DATED 10/31/2006) AND #PIP3042A (DATED 8/30/2004). I'VE SEEN ON MANY MANY FORUM POSTS ABOUT THIS ISSUE AND POSSIBLE FIXES, WHICH WHEN I READ DEEPER INTO THEM, SEEM TO NOT BE TRUE FIXES.

I KEEP HAVING THE DISPLAY SAY "REDUCED ENGINE POWER". I'LL BE DRIVING ON THE HIGHWAY, DOING 65 IN RUSH HOUR TRAFFIC, WHEN ALL OF THE SUDDEN THE ACCELERATOR NO LONGER ACCELERATES AND IT DISPLAYS "REDUCED ENGINE POWER" ON THE GAUGE CLUSTER DISPLAY. FROM WHAT I'VE SEEN ONLINE IT APPEARS TO BE AN ISSUE WITH THE THROTTLE POSITION SENSOR ON THOUSANDS OF OTHER SIMILAR VEHICLES WITH THE SAME ENGINE, CHEVY SUBURBAN'S, SILVERADO'S, TAHOE'S, ETC. I REPLACED THE THROTTLE POSITION SENSOR AND THE HARNESS (BECAUSE I HEARD THE HARNESS MIGHT ALSO BE AN ISSUE) AND I AM STILL HAVING THE SAME PROBLEM WITH MY TRUCK. IT HAS DONE IT OVER A DOZEN TIMES ON ONE TRIP BACK FROM WORK (80 MILES FOR ME). I HAVE TO PULL OVER TO THE SIDE OF THE ROAD (IF POSSIBLE) AND TURN OFF THE TRUCK, THEN WAIT A SHORT PERIOD OF TIME, THEN TURN THE TRUCK BACK ON. THIS USUALLY FIXES THE ISSUE, BUT IT DID NOT HELP ME WHEN IT HAPPENED TO ME IN THE TUNNEL AND I WAS GOING 5 MPH (TOP SPEED DURING THE "REDUCED ENGINE POWER" MODE, ONCE YOUR
