Ok so I am currently stuck on why I can’t hammer down on the peddle without my tt losing power or burping on me. I go to pass someone and I step on it and instantly lose power. it doesn’t seem to like running in low r’s without a pop or complete lose of power. My turbo doesn’t seem to keep a steady whistle either. More like a pulsating in and out whistle almost like it acts as to much air is getting to it. I do run a code and it’s for. Misfire from 3/4 and “random” cylinders. I put all new spark plugs in and rechecked connections and it still seems to do that. So……. I’m thinking coil packs are needed. Any thoughts?? Help a girl out. She’s in the middle of Washington just tryna get back home. Thanks 😌
