No, LoveWaffle. The second after Impulse traveled back in time, Neutron was instantaneously cured. You're operating under the assumption that Time Travel has a Delayed Ripple Effect, and that the past and future are operating under San Dimas Time .

This is not the case -- any and all changes made by Impulse already happened. Neutron, of course, has a Ripple-Effect-Proof Memory, with his memories suffering from Ontological Inertia by being too close to the time travel event horizon.
