D4 light is related to the transmission and the transmission computer. You can find It easily on Google.

I see this video about a a top dead center sensor. He just replace the engine head valve gasket. But you ill see oil on the ignition coil if you need to replace It.

To look about the throttle sensor, you need to have a multimater to see if It’s ok or not.

Before changing your EC, at last try this video inspection for rough (noisy) idle.The iddle that sound your car like a old one.

For the Electronic Control Module now call ECU u = unit. You should replace It whit the exact car model available in your nearest car scrap yard.
