[paul b]

We'll need to know if the codes come back.

Also, was the MAF disconnected in the past which triggered the code?

[saabsalltheway!]

will be doing another scan soon
car was serviced not too long ago but dont know if maf was disconected with ignition switched on
will be looking at ross tech wiki too
thanks paul
