how do you find the #1 firing cyl. on 1990 oldsmobile 88
since this car has no rotor i think the timing is off and dont no how to find the #1 firing cyl. is there a way to find it
If its a 4cyl its the one closest to the passengers side. If its a v6 its the passengers side front. If you plan on adjusting the electrical timing I wish you the best of luck since its impossible.
