I was going to take a picute but all I have is my phone and it's not good enough. SO I was reading here

And read this

 

For a while I had been getting a strange stumble when accelerating from low revs or at odd places in the rev range. Also, my tach needle (Autometer 5") would jitter at PART throttle but not at full throttle. Weird. I checked all my grounds, rerouted all the wires from my MSD 6A ignition to prevent RFI, measured resistance on all plug wires, and rebuilt the distributor. I even got a new alternator, but no solution.

I finally discovered that my fairly new distributor cap (Borg-Warner, brass terminals) had a ring of brass powder running between the terminals...CROSSFIRING! Interesting how the tracking seems to follow almost a magnetized path around the terminals. MSD type ignitions are said to produce heavy ionization in the top of a cap, and an old trick is to drill a couple of holes near the top of the cap to alleviate it. I had the holes drilled, but my rotor was slightly loose, I suspect that it may have slightly ground into the terminals and the residual ionization distributed the particles. I replaced the cap with a new one...the engine is smooth as silk now, startup instantaneous and tach perfect. An interesting lesson to be learned.

 

 

ANyways I have a similar problem, so I looked at my cap and I don't have the ring thing he was talking about but I do have white chaulky terminals.

 

 

Does this need to be replaced ? and if so will these work ?

Use Area code 92880 if it asks, (not sure if it takes you somewhere else if you have a different code.)

 

 

And I have searched for a fix but this is the first reletavly simple fix that I found so that is why I'm asking about it.

Well I bught it, 6 bucks can't pass it up. Now theres the rotor which my dad wil help me replace (I'm scared I will break my car) for a couple more bucks But since i put it on, i haven't had my problem, but then again it only shows it's face here and there so I might/might not have gotten it.
