1991 Corolla Very Sluggish and Slow! Need Help!!

#1
I just bought this 91 corolla wagon 2wd and it is very sluggish and has a hard time starting when it's cold but it still starts. It runs grate but just seems to have a hard time going up hills and getting on the high way due to the slow start of the car. I just changed the valve cover gaskets and the plug wires and distributor cap and plugs and it has 129,000 miles can anyone help me out??
