92B20GSR

i was driving down the highway a couple weeks ago and my car died. i was thinking maybe i just ran out of gas but something inside the dist. went bad (btw this is a 92 hatch with gsr swap) i replaced the dist. and car is running but now my vtec does not engage. Also there a small amount of oil in my throttle body for some reason. these are both mysterious problems to me. im trying to get this fixed because im supposed to be selling my car in a couple days.
