Hi all

Cleaned the car this morning and gave the engine bay a quick once over with just soapy water and a light spray down.

Now I have the P0629 and P0633 codes with rough running. I have searched these codes and seen there is a fuel pump and a key program issue by the look of it.

Guessing that these are not right or false codes as the rough running feels like a heavy misfire and a very rich smelling exhaust.

Assuming that there may be an open circuit hidden somewhere, that is otherwise masked when the engine bay is dry.

Anyone else had a similar experience or thoughts on the matter?

Thanks in advance ☺

 

Try clearing the codes and see if they recur. The rough running is probably the limp mode.
