'04 discovery trouble codes

[john booko]

Just spray washed the engine compartment of my wife's 2004 discovery. (Maybe not such a bright idea.) Now the service engine soon light is on. Took it to Auto Zone to read the codes. They are P1129, P0305, and P0135. What do the codes show that needs to be done?

Check for water in the air filter, either way clean the MAF sensor with MAF cleaner.
