After switching out my intake manifold, I drove the car tonite. It started right up, but has a low speed miss that goes away around 1500 rpm, but comes back under any load. I checked the timing and it bounces around from 15 to 25.
I haven't found my wiring instructions for the MSD, so I just reattached everything from memory-not good...after looking for loose connections, I found a black wire that comes from the bottom of the distributor. It looks like it had been connected to something...There is a red/black wire coming out of the cap that is hooked correctly to the coil. Anyone know if there should be a third wire connecting from the distributer to the coil (and which post does it attach to)? Thanks.

I'll be back home Saturday. I can refer to my instruction sheet then and post the directions then.

Thanks for the offer to check your instructions....I checked on the web and looked at the instructions from the MSD and Pertronix sites. Everything looks fine, but they do not show where the black wire at the base of the distributor connects. Does anyone know if this wire goes to the negative terminal or to ground????

Hey ignition gurus, I have the original Pertronix 1. I haerd about the Pertonix 2. Is that one better than the original one? If so then why?

The MSD installation schematic for the Pertronix shows the black on the distributor connecting to the white wire on the MSD. It shows the red on the distributor going to ignition and red on the MSD. The coil should be connected to the MSD orange to pos and black to neg. If you want I can scan the drawing and email it to you.

BTW, I know nothing about Pertonix. This is listed as Pertronix Ignitor?

I have it wired as you described. It still has a bad misfire. There is a black wire that connects to the bottom of the distributor (just above where you loosen and tighten the hold down bolt). This wire is now hanging loose. I wonder if it is causing the misfire? Any ideas?

Rolling Thunder

Any chance it should be connected to ground? I'll read through the troubleshooting section and see if anything seems to fit.

Sorry, nothing else. Come on Pertronx guru's, help Doug out.
