YASER Posted December 8, 2017 Share Posted December 8, 2017 Good to all the members of the forum. I need help, I have a mack E7 350, year 95, with bosch injection pump, the question is that the engine accelerates only up to 12-14 RPM and then goes back to normal work. Which or what would be the possible causes and the solution, thank you for your help, thank you Quote Link to comment Share on other sites More sharing options...
dickbuick Posted December 8, 2017 Share Posted December 8, 2017 I am thinking throttle position sensor Without scanner or computer to check throttle % I would try to turn idle up with cruise control switches but that depends on what your parameters are set at To change the TP sensor I could only buy the hole pedal at about $400.00 Quote Link to comment Share on other sites More sharing options...
YASER Posted December 12, 2017 Author Share Posted December 12, 2017 Thank you very much for your help, I will try to try a pedal from another mack before buying a new one because it can not be returned. Do you think that the white smoke of the morning at the moment of the start is for the same reason? Quote Link to comment Share on other sites More sharing options...
