Oldsmobile never made a car named Royal Brougham
ebay.com and or any GM dealer.
It seems that they most problems with the 93' Oldsmobile cutlass supreme would be the engine and the break. Those seem to go out the most on this car.

What do you mean by what order. Go here pick the proper engine and you will get your answer. http://autorepair.about.com/library/firing_orders/bl-oldsmobile-firing-93.htm
Yes what do I do
On the 94 it's behind glove box in a vertical position. Lots to take off to see it.
Around 27-29 highway is possible.
120 hp is the power of the Oldsmobile omega 1974 engine and its maximum speed is 93 mph.
