CEL P1128, P1130, P1123, P1125

Having read the posts about the P1128, P1130 generally being an issue with the MAF we have a slight variation on this and would value some input. As well as these two codes we also have P1123 and P1125, essentially the same but for a lean condition.

Is this indicative of something significantly different? It seems likely that the MAF should be blamed but any comments or input would be appreciated. Are there any other readings we should look in to that would help the diagnosis?

Any comments much appreciated!

Oh one more thing, is it wise to swap MAF Sensors between cars to see if the error codes go with the one thought to be bad? I'm not convinced of this plan as my car is the one with no error codes :o)

Swapping is okay as long as the two cars use the same MAF (they can be different) and there are no funny changes (like filters, manifolds, ecu, etc). It is usually better to put the good one in the bad car to see if the bad car gets better.
