hi guys engine management lights been one for couple of days so plugged a reader in and found three fault codes:

po102- mass or volume Air flow A circuit low

po171- system too lean Bank 1

po113- intake air temperature sensor 1 ciruit high


any ideas what this would point to? when i cleared the codes the car turned over for ages before she fired, normaly starts right away, but now seems fine. any ideas? cheers guys

 

I guess if the maf sensor is knackered this will through out the fuelling resulting in the 2 other errors?
