Longhaul Posted January 25, 2019 Share Posted January 25, 2019 I have a 93 mack ch613 with a new remack e7 350 as of last year. I believe it's a v-mac2 (bosh injection pump with a Electronic pedel) I'm now getting a bad misfire everytime full throttle no matter where RPMs are. If I may it she falls on her face. For the most part it only happens when I floor it but i think i noticed a little hesitation a couple times coming off the pedal. So far I changed the filters and added locus injector cleaner. Any advice would be appreciated Quote Link to comment https://www.bigmacktrucks.com/topic/55405-e7-350-misfire-at-full-throttle/ Share on other sites More sharing options...
JoeH Posted January 25, 2019 Share Posted January 25, 2019 Change the fuel filters again. My 95 mechanical e7 350 did this last year. First set fixed it for a couple days, replaced the filters again and it hasn't been back since. Also make sure you oil the filter O-rings before install, or you'll suck air in.

theakerstwo Posted January 26, 2019 Share Posted January 26, 2019 Check your fuel pressure after the filters uner load. Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/55405-e7-350-misfire-at-full-throttle/#findComment-414136 Share on other sites More sharing options...
