Bad plug???
93 T-78 FD, I was driving 40 mph car began to run rough and back fire, I pulled over the car died and I couldn't get it started again. When I push started it the car would run but only if I kept on the gas and it back fired alot. I got it home pulled the leading plugs and I couldn't get spark on one of them. I will put in new plugs tommorow and see what happens.
I am using RX-8 plugs. Is this something that would happen if one of the plugs was bad? Thanks Erik |
Which plug was bad? This makes a big difference... you can have a trailing plug (top ones) bad and not even NOTICE. So I'm assuming it was a leading plug. Why would you use RX-8 plugs? I mean... the regular RX-7 plugs work fine for most people....
I run BUR9EQP leading and BR10EIX trailings... what are you using. |
One of the trailing plugs was bad. I am using RX-8 plugs because the shop that put the car together said they were the best to use. I am only going by what they told me.....regular RX-7 plugs are probaly less expensive so I wouldn't mind using them if there were no difference in performance.
I am not sure what are in there for trailing, I would have to ask. The shop also said I would not have to change my trailings. I don't understand this. Do trailings last longer than leading plugs since the leading provides most of the power? I am still learning so please bear with me with my newb questions. Also would a bad leading plug cause what I described above? Thanks |
Yes, if one of your leading plugs was not firing, it would basically be like running on one rotor, since the trailings only provide waste spark.

Went to the dealer and picked up a set of FD leading plugs , put them in and the car started up right away.
