MY93 MAF Sensor Problem?
I am getting slight hesitation sometimes as I come on to boost, after a bit of research on here I wanted to eliminate the MAF and Lambda sensors. I have new coils and PFR6B's recently fitted.
I read that I can check the MAF by unplugging it and the engine should die. When I unplug the MAF the engine does not stall, but it does run rough (revs hunting). When I plug the MAF back in the idle becomes smooth again. Is my MAF ok or is it on the way out? If it is knackered do I need to replace or is it possible to clean it?
Also is there a way of testing the Lambda sensor??

it does sound like a failing maf but the earlier ones are generally quite good mafs. Personally if it is running standard ecu then I would do an ecu reset and then disconnect the maf. It will probably stall.

So if I reset the ecu and then disconnect the MAF and it stalls, does that mean it is ok?
