Bling + Low Voltage=Trouble
Truk4U: You and Mango may have guessed something, but the TPS failure low, meant low voltage to the Prevost guy, the Detroit Diesel guy said to replace the sensor. The Bling lights were not on when this occurred- so the Bling cannot be blamed for this. The exKing of Bling said if I could not find a loose connection, then replace sensor.
As I reflect back trying to recall any signs of the failure coming, when I cranked up at Santa Fe the only unusual thing was the engine sputtered a few times and sounded like it was on about 2 cylinders for a couple of seconds, and then cleared up and ran normal. I thought that may have been because of the cold nites, high altitude, or like me, getting old and slow to start.
PS Mango, if Lew had one in his Ace Store, it is so small you probably couldn't find it. If you get a hold of one those Lew translators whatyoumacallits let me know.
