Tloftis Congratulations!  Your peers have given you enough reputation to put you into the fist level!

Default DIS ignition testing

I have a 1997 Mazda that has a wasted spark. there is only one spark plug that I can get a decent reading off of and look at a waveform all of the other spark plugs will not produce a normal looking waveform it's always been that way but I don't understand why just one spark plug will do that it seems like all of them or at least three of them should read correctly.

Is they're away to read these individually without having to purchase the expensive snap-on accessory? I'm talking about the one that has like eight plug wires hanging off of it and you connect to it and then it is able to read all the cylinders. I don't want to pay that crazy kind of money for that
