I have a 95 GT. I have added MAC longtube headers, off road
H-pipe, MAC Cat-backs. My timing had been advanced by previous owner to 15 degrees. (If I'm reading correctly. The small circle that is over the dampner is where I'm reading the timing with the SPOUT unplugged) The proplem is that after I added the headers and stuff I would hesitate between gears at WOT. I am also pinging at WOT. I've backed the timing down but my Idling goes all to pieces. Is there something else that I need to do or am I doing something wrong? Please help.
