0 alex g Posted October 22, 2020 Share Posted October 22, 2020 Did you change or check injectors while heads were off? Quote Link to comment https://www.bigmacktrucks.com/topic/64666-1997-mack-e427hp/#findComment-462814 Share on other sites More sharing options...
0 Lmackattack Posted October 22, 2020 Share Posted October 22, 2020 WELCOME TO THE ELECTRONIC E7.. they just lack power and are sleepy. you will need injector upgrades and possibly a ECM tune to get them to wake up and run like they should. I have only driven one E7 that performed well in stock form and I dont know why it was better than the other 10 I have driven Quote Link to comment https://www.bigmacktrucks.com/topic/64666-1997-mack-e427hp/#findComment-462815 Share on other sites More sharing options...
