65 mustang stuttering between 3000-4000 rpms on acceleration. Timing advance set to 6 degrees. New msd blaster 2 coil and plugs. New intake manifold. Any suggestions? Thank you
Try a full tune up of plugs, wires, points, condenser and new distributor cap if not previously been upgraded. Worth the upgrade even if the symptoms are still there. Go for the above suggestions... fuel filter is a real suspect.
