I posted on here a while ago and the good Dr. Banks suggested I had MAF trouble. Let me repost what my original observations and then add my latest observation. Whilst accelerating hard, change gear, re apply throttle - Orange knock link leds light up but only during the re application of the throttle - not when under full WOT. Idle is fine but now I have become aware of the fact that under a light throttle at moderate speed, the exhaust note is, well, fluffy!!, not crisp as it is under WOT... does this indicate anything other than MAF fatigue??

Thanks
