Hey guys, recently installed some pacesetter longtube headers on my 1998 mustang gt. To start off, it was the biggest pain in the a**. I didnt use pacesetters gaskets though, i bought sce gaskets. During the install i couldnt disconnect the egr tube from the manifold so i cut the tube and decided to delete the egr. I used a block off plate, capped the vacuum, and put a plug in the header. After all of this i have a misfire and its coming from the drivers side header. Did i incorrectly delete the egr? Could an exhaust leak be causing the misfire? Any feedback would be great, my car ran perfectly fine before the long tubes so i am at a loss....I am getting a new tune from sct tonight for the egr but im not counting on that fixing it. If all else fails i might just get new gaskets from ford to see if that does anything.
