Get this guys, I'm gettin my 95 GT ready for nitrous and when i took my timing back to 10 degrees... I've got cylinder misfires in 1-4 but cylinders 5-8 are fine. Its a new ignition set up, MSD yada yada. Ohmed out the O2's and there the same. Any ideas guys? Need major help, won't spray the car until i get it fixed.
