89 Civic 16 valve Auto 200+miles (not sure how correct that is), Bone stock.

Two days ago I was driving up a hill and my car began to shake really hard and struggled to go over 40 mph up the hill. I stopped at the nearest stop light and it shaked so bad that it seemed like it was going to knock off right there if I didn't give it gas. Came home, went to change the spark plug wires and noticed there was Oil in the #3 cylinder. I automatically think it's the cylinder seals and go order some new ones, come back two days later and take out the other spark plugs to see what condition they're in, spark plug in cylinder #2 has burnt oil on it and some oil around it. I clean everything up and replace the seals. Put the new wires on and start it up, nothing has changed. It's idling way too low and feeling like it's going to knock off everytime I come to a stop, slow down, or go in reverse. I don't know what else to check! Anyone willing to help a new civic owner?
