I have been fighting a high speed skip in my car for about 6 weeks. It was fine for 18 months and this started and is getting worse. Checked everything I can think of and anyone has suggested to no avail. It has to be ignition and everything in the car is MSD. I look at the MSD site and they have a tech forums section. I look and see no posts about a similiar problem so I post my issues, say what I've done and wait. I get a reply to run the power feeds and the crank trigger wires this way. I reply and ask about the power feed wires again and ask what the minimal voltage should be. It's been 5 days and no reply from techguy. I'm like why offer a site with tech support then not respond to the questions the customers ask? If the darn car ran fine for 18 months it seems odd the wire location or power feeds would be a problem but I moved them anyway. The coil could be breaking down or the two step switch is going bad and acting like the high side RPM chip is in it or something would be nice but they haven't even said screw you and you're stupid problem, nothing. How sorry is that? RM.
