I need to know how to remove the intake off of a 1990 mercury grand marquis 5.0

is it fuel injected or carburated usually its just a matter of pulling off the carb or plenum from the top of the intake and then the valve covers and move all the wires and **** out of the way then you should have access to 10 or 12 bolts un bolt them and use a thick flat tip to pry the intake from the heads. but make sure all the bolts are out before that and pop should come right off
