Check engine light is on

I bought the car listed above. The check engine light is on. Took it to smog guy he said on the scanner it needed the Idle Air Control Valve, so I bought and put it on but it still says the system is bad and the idle goes up and down. Now it says on the scanner, I need the torque converter clutch solenoid circuit is out, now on the scanner I have nine things wrong and it is misfiring on five of the six cylinders. I am not sure what condenser is on the spark plug? I was told that two of the front condensers are bad and I will need to replace them. All I want to do is pull my hair out because this car has done nothing but cause me to spend more money on it. I have only had it a month. I have bought wipers, brakes, headlight, IVC valve and it still runs terrible! Help please!
