Shaking under boost

[GrimJack]

At this point, I'd seriously consider plug wires. If you had oil sitting between your valve covers, and the plug boots were sitting in it, they are more than likely toast. A shorting wire will cause these symptoms easy.

Is there anyone close by that you can borrow a set of wires from? Or do you have an old set lying around?

The valley as well as the plug boots were SOAKED in oil. I think i still have the old wires in the storage space under my house. Maybe I'll try those out tomorrow.

Just out of curiousity... Would it change your opinion on the wires any if i said that it wont shutter at low boost(i guess 4 or 5 pounds according to the gauge)

Not at all. If the wires are shorting part of the spark charge, it can easily fire a big enough spark to ignite properly at low load, but not have enough spark to ignite completely under heavier load.
