I have an MTronic 441 that is about 9 years old, and very, very lightly used, but randomly won't run/start when it is hot. Is this definitely a coil issue? That coil is wicked expensive. How can I diagnose this? I'm afraid that if I take it to the dealer, they won't be able to reproduce the problem. Does that matter? Can they still test the ignition module to see if that's where the problem is? If not, what should I do?
