When waiting at a stoplight the engine is starting to stumble from a smooth idle to a jerking miss. As long as I ease into a long drawn out acceleration from the light the car will not embarrass me by acting like choking animal and entertaining those not affected. When going up an on ramp it gets really interesting. So itís like any time I need power to get the car going does it do this.

I did take 1000 grit sandpaper and shine the contact points in the distributor cap and rotor.

I made sure the counter weights and swivel underneath the rotor are OK.

Could it be the vacuum diaphragm off the side of the distributor for the acceleration issue?

Whasss Sup?? Thanks everyone!!

You might want to put in a new set of points/condensor. When you sand the points, that increases the dwell or gap. This also effects your timing. I would check your dwell/gap first, then set your timing. Let us know what you find out.

You've got mail.

Another thing just occured to me. You have a 71. If you have HEI then it has been changed from points to HEI. 71's came with points. A common problem/mistake with this change is that the HEI takes a full 12 volts. If you are still running the original "hot" wire(the wire on the negative side of the coil) from the points-type ignition, then you are not getting 12 volts to the disty. That wire has built-in resistance which was required for points type ignition. Hope this helps. -Mark
