You're not alone, bro, when it comes to non-owner friendly vehicles (like everything since the early '90's).
Code 52 is logic module fault-apparently the computer has an internal fault. Believe it's under the hood, front left side.

OK, get a stethoscope to listen for the telltale clicking of the injector when it is connected to the listening tool.
Also, one can buy a noid light that connects to the harness to see if it is lighting or pulsing electricity to the injector when running or cranking.
A bad or plugged up fuel injector can cause the skip or miss in the engine.
Also, a bad or burnt 'valve' can cause this symptom.
Do a compression test to see that all of the cylinders have the same compression characteristics.
That's all I can think of right now.

This engine may just be wore out. Did you check the compression?

Hello! Although the Throttle Positioning Sensor (TPS) has been changed the symptoms are pointing at it...When the new one was installed was it mounted with the throttle valve held shut; Then rotated counterclockwise until the mounting holes lined up? Send a comment...Guru..saailer

If no one has removed the EGR valve and inspected and cleaned it that could very well be your problem. If a pice of debris, ( chunk of carbon) has become lodged in the EGR valve that will definately cause rough idle and stalling. There are 2 bolts that mount the EGR valve to the intake manifold. center rear ov the intake manifold. You will have to disconnect 1 elecrtical plug on the EET ( Electronic EGR Transducer) to get it out and the EET has 1 vacuume supply hose to disconnect also. takes about one half hour to pull it off and reinstall it. When you take it off, you need to inspect the mounting surface and 2 exhaust gas ports. if a large build up is present you need to clean really good. a wire bore brush and carb cleaner works well for me. make sure the valve moves and seats fully. if you can apply vacuume to the top port and make sure the valve opens and closes when vacuume is released. If it does not, or you have a vacuume leak in the EGR valve you would need to replace it. they run about $80.00 to $100.00 at your local autoparts store. Also replace the EGR gasket when and if you reinstall the old EGR valve. a new valve typically comes with a new gasket.
