I have a 2003 mack cv713 with AI 460 engine. Having issues when I am accelerating full throttle. Some times it acts like you only have it half throttle and then all of a sudden all the power will kick in. It gives no check engine light and runs smooth at all times. I replaced the electronic pedal, intake pressure sensor, checked and cleaned all grounds, all new filters, new EUP pumps in the last year and nothing fixes it!
