Revs Drop when taking my foot off the Accelerator and when Braking

[Znistige]

I've noticed that when I take my foot off the accelerator pedal the revs drop rapidly to 1.000 and also when I brake it drops.
Does it have anything to do with Fuel ? or Injectors? I use 95 Octane all the time and I usually put Injector cleaning fluid.

Any Help will be appreciated !

Look at your intake pipe that goes from your air box to the block, it may be split or loose and is sucking 2 much air and choking the engine causing it to stall out, I had the same problem a few weeks back, my intake pipe was loose an slid off

If not that try plugs and leads

Yeah it's a bit loose but I saw a small rubber cut where air box is
