Well, 99.9% of the time code 43 is your O2 sensor so you should start by replacing that. That will most likely fix the code 43 problem and it might fix the code 15 problem.
Code 15 is Ignition Output Signal. I dont know what that consists of, but it is ignition related so you should start by changing out your cap, rotor, and spark plugs. That is always a good start when dealing with ignition problems.
You should definately start out by doing the O2 sensor and resetting your ECU. See what happens after you do that. There is a chance that fixes your problems.
