it was an older Si with just a short ram intake, i know the kid he is from my town. but any ways, i thought i had fixed the issue with the melted vaccume line but i was way off with that. i decided to do a complete tune up and when i pulled out my first spark plug, the electrode was GONE MELTED MISSING! i was so besides myself when i found this. to make a long story short every other plug was the same exact way, how my car ran from sat night till monday no effin idea. if i could figure out how to post some pictures on here of the plugs i would do so.
