No CEL light yet though ...

pete, try doing an ecu reset. the problem with the maf failing i find is that as it starts to fail. the other sensors on the car tend to try and compensate for its failure,so the car doesnt do anything seriously out of the normal.by doing the ecu reset,your basically draining the memory in the ecu.so after its done the car/ecu cqannot compensate for the maf.so the car should run worse than before ,as its now trying to rely on a faulty sensor.=rough idle + might cut out.
hope thats some help, pete.

Pete you may not be wrong, mine was gradually getting weaker on the wideband AFR (in open loop) so removed the MAF (new age ) and very carefully cleaned the two inside electronic bits with cotton bud and methylated spirit. Amazed how much **** came off on the cotton bud. Refitted MAF and AFR back to normal and wallet still intact!
