Hello together, I bought a Mustang and drove with the over 700km at a time (Berlin-Stuttgart) shortly before arrival the engine started to stutter, at the beginning only briefly… the next day permanent. It is more of a knock, from 2500RPM sounds like 1.2 cylinders do not ignite… Before that it has gone off properly, especially at upper speeds. Verbated on the engine are: Alukopfe Edelbrock E-Street, Edelbrock Vergaser 1403 500cfm, Roller tipper lever 1.6, camshaft no indication n, Summit intake spider. I went out of the worn-out ignition system and changed the following after the order: spark plugs, ignition cable, distributor of Petronix installed. Now it starts even better, but still the same symptoms… I controlled ignition pint, at 35 degrees total timing unchanged. Since the highway did not drive at all and that makes me sad, hope someone has a good tip for me? MfG Oldilove
