New distributor originally faulty or ECU spike? 1993 Proton Gen 2 1.3 GL
Any help gratefully received. New distributor was put in my car, within 1 week it failed (according to the breakdown service). The company I purchased from have said it could be an ECU spike that has blown the ECU and I have to return it for inspection. Is it possible to tell the difference between an originally faulty distributor or a faulty caused after purchase?
