hi guys im new on the car scene and bought a 1987 z31 as my first car i went 5 hours to get it , drove it back having no issues , it was a everyday driver for the guy i got it from . when i got back i took it around the block one time and i brought it back and turned it off and washed it . then after a little bit i went to move it so my famliy could park , i didn't even get a few hundred yards and it cut out on me i lost all of my rpms and couldnt gain anymore , the car shutoff and i was checking all the fluids etc etc and i saw the oil was at the bottom of my dipstick . since then i had too park it and itll turn over but wont stay running unless the throttle is open , but it wont rev or anything its just a rough idle , , im doing my best to learn so all input is a appreciated
