Hi Dave, Thanks for your reply and waveform, what `scope was this taken from? I will use Pico in future as the Crypton paper printouts do not transfer too well. After following your instructions to post the `scope traces Sean and I are getting the Bosch traces like yours on the left and the simpler Fuelparts one on the right. I have now removed FP meter and fitted genuine with believe it or not worse results, at idle now the oxygen sensor will flat line full rich for a couple of seconds or so before resuming switching, something it never did with either of the two earlier maf meters, so looks like I may have a duff new one !! Sean if you read this post I`ve edited my post of 16th, if you re read that one this one might make more sense, on the other hand......... Best regards Roger.
