    I have a '14 freightliner cascadia dd15...im no mechanic but know a lil something...my truck has been shaking alot driving feels like its jumping around..especially when i try to go fast...bad performance and is eating up my fuel big time!! So i know i got a bad fuel injector...but my ? is ..how do i know which one is bad?? And how would i know if the others are bad or not? Do i soely rely on the dash telling me which one is wrong? Also i heard something about weight or pressure having to be a certain # when installing..can someone explain that to me??

    As far as the shaking goes get those Kingpins checked out, Alignment and have some one look at the front suspension. A 2014 with what 500 k 600k miles? Maybe better to change all the injectors they may be at the end of their life cycle. Get it to a dealer.
