2015 GT 63k miles 6speed. Hey everyone I was roll racing a buddy today and I was in 4th gear at around 3-3500 rpm and when I floored it, my car didn't really go and had a flashing check engine light that went away after 30s or so. I read the codes and it came back as misfire on cylinder 2,5,6, and 7. And a general misfire code. My car has always had a sort of pulsing idle that makes the car shake a bit but the rpms don't change. Ive changed the plugs about 1k miles ago with Ford OEM plugs all pre gapped. I was wondering if anyone has any idea of something is wrong or if I should of just not floored it at that rpm and gear.
