So I had this brilliant idea of "that ignition coil is 50 years old, let's change it". - Worked fine. Just had to change it. I used a new NGK coil and Delco Condenser (I guess that's just a radio suppressor bolted to the coil?)... hooked everything up the same way, and misfire at low RPM. If you get her to about 2000rpm, no misfires. Thought perhaps I've got a bad coil or something so I threw the original Delco coil back on. Same problem. What could've happened? This car was running perfect beforehand. I've checked all the other wires and cables and grounds. I can't have the coil wired backwards, could I? The condenser and distributor wire were together originally, and the red power wire was by itself.. and I'm pretty sure the red goes + and the dist/conden go - On top of this, I been trying to do it in my garage and I'm in the process of suffocating myself with the fumes... so it's been an interesting morning.
