    2013 Ram 5.7 cam

    hey guys, I just installed a Mopar non-MDS cam in a 2013 Ram 5.7 Hemi to replace the cam with the missing lobe and junk lifters and now it won't start unless I hold the throttle wide open. I disabled the MDS and it feels like its only firing on 4 cylinders and stalls under 2,000 rpm. is there something else I need to disable or enable to make it run smooth and start? The timing is set correctly and I am stumped and it is going on two weeks with this problem. Any help would be great. thanks in advanced

    I can't find the part # for the cam. it is a Mopar non-MDS cam with stock profile and Mopar 05038784AD lifters. probably doesn't help I know. I think the box got tossed out during shop clean up and i was too stupid to write it down
