Challenger Posted February 2, 2014 Share Posted February 2, 2014 MP7 04 emissionsIs the malfunction light on? Do you have any codes?Did you monitor your fuel pressure? Are you sure its steady while it looses power?Have you monitored the boost pressure?

Kyle 537 Posted February 5, 2014 Author Share Posted February 5, 2014 I ran the boost psi test drive with drive a week ago but the truck never hiccuped during and every thing looked good. The truck is always out so for get much time but the drive say it's doing is occasionally on longer drives. It did have egr valve codes.

Challenger Posted February 6, 2014 Share Posted February 6, 2014 Probably related to the egr code. What was the code? Quote Link to comment https://www.bigmacktrucks.com/topic/34498-07-mp7-pre-dpf-power-loss/#findComment-230766 Share on other sites More sharing options...
