I’ve been having really bad misfires where i get sent into limp mode everytime, got a brand new downpipe because misfire melted stock one. New plugs, coils. I have a catch can. Hole drilled in bottom of intercooler. And have throughly cleaned throttle body and intake. And STILL i misfire on highway speeds and get sent to limp mode. I have run out of things to check and im so lost on what to do :/...
