Ok so I have managed to get the code and it is throwing code 9 CYP - cylinder sensor. I have read that this means buying a new distributor because the censor can not be purchased by itself. Is this something I need to replace now? Will it cause harm to the engine? I just replaced the rotor, cap, and wires not too long ago.
When I used to have this problem and replaced the same parts you did I found that in the warm weather it wasn't a problem. The car ran decent. But for whatever reason once it got cold the car idled horribly.
I ended up buying a new distributor from Distributor King from ebay cause they had the best price. Everything has been find since.

--Yes theoretically one cannot buy a new sensor anywhere without buying a whole new dizzy housing. OEM will run you around $290 at online OEM sites. Advantages: A whole new dizzy housing means three brand new sensors and a new housing wiring harness. Performance/mileage should improve. I think all these sensors degrade with time to the point I'd say replace the housing every 150k miles/10 years.
--Take off the old sensor, inspect the wiring and clean it up. For some clues, see http://honda.lioness.googlepages.com/distributorbearing . No guarantees this will fix the problem.
--Go to a junkyard and pull off a second-hand sensor. OEM shop manuals actually do have directions for removing the CYP sensor.
If you do any kind of rebuild, consider replacing the o-ring and maybe the oil seal as shown in the illustration at the site above.

If you're lucky there is just a wire to the sensor loose. You really want to get a shop manual and go through the diagnostics for this code. Best case your fuel mileage is worse. Options once you confirm the sensor is not working:
