Misfire issues hellllp
Hi, I have a 2011 Ecoboost. Truck has 106k, I have non catted y pipes and a sct tuner with custom mpt tunes. Truck ran good for about a month then started throwing misfire codes so I replaced all spark plugs gapped at .32 as well as new msd coil packs. I immediately seen improvements on acceleration and my mpg went up as well. Now when I go into hard acceleration it’s throwing the misfire codes as well as the truck running lean. I have seen where guys are drilling a weep hole in the bottom of the intercooler and was wanting some more info on this. I reached out to a friend that is a mechanic and he was saying that doing this will result in loss of boost. Any facts to verify that will happen? When I return the truck back to stock I’m not having issues. It only acts up when I have the tune installed. Being that it only does this with the tune installed and it throwing a lean code if the lift pump isn’t supply the high pressure fuel pump with enough fuel be a possible issue? Again I’m tired of having this issue and looking for any info on this issue. Thanks
