Alrighty, I'm glad to report that how things are going on my current tank of gas, that i'm getting 23MPG so far, for a quarter of a tank (3.425galons) I've gotten 79.5Miles, is roughly 23 miles per gallon... So far so good...
The reason this update was slow, was i haven't driven much these past couple weeks, and so i haven't used a full tank yet.
I'm really glad it worked out... The car still shudders a little, but it doesn't loose fuel like it was, I'm wondering if the shuddering is unrelated to the gas problem i had...
