aloha, i recently had some problems with my truck stumbling but thanks to the help i got here i was able to fix it. i have a 2001 350 that would lose a considerable amount of power going uphill. i changed injector o rings, pedestal rings, hpop rings, icp, as well as did a ebpv delete. now all i have to do is drop tank and clean the pick up tube as well as check for cracks (this is just for good measure). my question is that my truck went from getting 20+ mpg to less than 10 after all of this was done. could i have messed something up by deleting ebpv or maybe nicked a fuel line somewhere. i am stumped. i also have a strong smell coming from exhaust but not much smoke. any help would be appreciated.
