thats kind of funny, i changed the oil in my car then my oil pressure was doing the same thing and BOOM... spun a bearing just that quick..
Cool... I have to pick up my header gaskets tomorrow anyways so I will grab a sending unit switch deal too, after I make sure it isn't just a loose connection. First i have to figure out where it is though...
yeah, sounds like the connection is loose, or the wire is frayed and it grounds out whenever you accellerate. i had a frayed wire on my 95.
