Hiundai问题有帮助

Hello friends, I need your knowledge, I have a problem with a Hiundai Elantra year 92, they took it towed to the workshop with ignition problems, review it and notice that there was no spark in the cylinders but if in the cable of the coil, so it changed cables, cover and distributor rotor and walked well one day, then they took it to change the power spark plugs and for a problem of oscillation in the minimum Let it change autolite spark plugs by Bosch Super Plus并清洁空气输入负载，当您完全付出任何东西时，我不想再次将电流转动到火花塞中，如果它不存在，则是注射器中的脉冲，有人可以给我一只手，我需要事先解决。
