Hello again,

it has been an eventful 2 weeks - we have taken everything apart again and checked wires and the (new) spark plugs again. The engine was running fine and the shaking stopped. No more misfire error codes. Fuel pressure was normal.

During the test drive, a new error code showed up, P0118, which indicates ECT (or CHT) sensor input too high. The ECT sensor has now been replaced, but the light is still showing up and comes with the same error every time.

I have now found out, that the CHT sensor sends data to the PCM, and if the input is too high, the PCM might shut down a few cylinders in order to prevent overheating. The engine was running fine but started playing up slightly again yesterday. It has been dry the week before and we had some heavy rain yesterday, I am wondering if this could be related.

I'm having trouble sourcing a CHT sensor quickly here and we will check the wiring in the next few days. In light of this new error code, would there be something else we could check?

Thanks as always - getting there!
