What's going on here? I've had the same set up for 20 years (2.0 D-Jet with MSD 66AL)
Now at 4500 rpm the tack drops out, then bounces wildly. Also if I use the directional signals, the tack drops. Ill try to add a little video |

QUOTE(IronHillRestorations @ May 11 2026, 08:01 AM)  Try changing the points Thank you. I will try that. Since I've owned the car (25 years +) I have never gapped the points. I thinks Slits told me they were useless with the MSD, and to just leave them alone. |
