Sputtering, jerking while driving

[Papabug]

If it stops when the tank is full my moneys on bad gas / water in the tank. I vote for the gas treatment advice.

Well, gas treatment isn't working. It sputtered all the way to work today. The tank is still full though.

On to the next thing. Rotor cap...

I had bought the spark plug wires already... so I went ahead and changed those out just now. I took it for a test drive and there wasn't any sputtering!

I think I may have found my problem! I'm still going to inspect the cap though and post and update on it.
