So this problem turned out to be suuuuuper easy to fix. I was just
about ready to start replacing vacuum lines when I decided to check
all the plugs just in case... They were all in *really* bad shape.
None of them were gapped correctly and one had detonated. I'm
guessing this is what caused my "acceleration" issue. I replaced them
all with Bosch Super Plus copper core plugs, replaced the cap and
rotor, and plan to order a set of Magnecore wires. (If anyone has had
great experience with another set of reasonably priced plugs and
wires, or if anyone has a specific source for Magnecore wires please
let me know.) I feel a little stupid having taken the previous owners
word regarding the plugs and wires. In the future I will definitely
have a wrench to check plugs when I'm looking at a used car.
Getting to the snow is my priority till the end of March, but come
April I will definitely be replacing the valve cover and oil pan
gaskets, the air filter, and all of the vacuum lines. I was leaning
away from working on this motor much since I was planning a swap, but
now that I'm learning about the more creative options where I can use
this block I'm open to any maintenance suggestions. Additionally, if
anyone has after market resources to check out please send them my
Thanks again for all of the help!
PS. This weekend will be my first opportunity to try out my Green
Diamond Icelanders in the snow !!
