Default Issues with misfire or fuel?

hook up a fuel pressure guage and see what kinda pressure you're runnin. don't really think its a fuel problem since it wouldnt wait till its warmed up it would run like crap from the get go. sounds like you might have a burnt wire or the opti you got was junk. make sure your plugs are gapped right
