ok i have a 93 lude..... my problum is that about a month ago my RPM's started jumping around and then the car would just shut off, and this was when it was wram. but then it got to the point where it would just turn off out of no where and wouldnt come back on....... so i dont know what to do with it so could someone help me out? also i was wondering if anyone knew how to do a self diagnostic test? thanks
