I've replaced the fuel filter, spark plugs and spark plug wires, ignition control module and both coil packs. It still wont go over 20 mph up hill and on flat surfaces takes a while to get up to speed. The engine and transmission are both running good and there's no leaks. It's not over heating and oil pressure is great.

Welcome to the forum, I'd use a gage and check fuel pressure. Check for trouble codes. Check compression. Make sure the exhaust isn't clogged.
