A properly layered wound coil of the correct AWG with vacuum impregnated varnish would never burn up. Using under sized wire random wound is when problems started to occur. With a misfiring spark plug, first thing to take a beating is a zener diode that protects the gated bipolar transistor. Never was permitted to make those large enough due to cost restrains.
If that shorts out, full current flows through the coil, uninterrupted and no more controlled current. We call this a chain reaction.
Use to have a separate ignition module, bean counters came along, know its driven by the ECU, why are you making these separate. To reduce maintenance cost. Screw that, make it a part of the ECU so we can make more money saving all that extra wiring and module case cost. What about the consumer? Screw the consumer. AT controller, cruise control, and others also had separate modules, now all part of the ECU.
Friend is having cruise control problems in his VW, his dealer claims its in the ECU, wants 1,300 bucks plus labor and programming to install it. Screw the consumer. Really screw the consumer.
See my daugthers Kia Soul is using coil on plugs, if one goes bad, just replace that, not the entire module like in the Cruze.
Usually keep my valuables in a safety deposit box. Should get a large one for some of these way overpriced car parts. Sure started a many chop shop businesses.
