Right was bored in some traffic today so started playing with my car revs. :whistle:

Noticed when i give the throttle a quick jab the needle and revs drop for a split second before rising only very slight but noticable...

Also on my drive home i was on overrun in 3rd from about 40mph noticed not everytime but, if i depress the throttle very slightly i get only what can be described as a pop/cough from the exhaust.
Doesnt sound like a normal exhaust pop more airy like a release of back pressure if that makes any sense..?? :headhurt:

Car drives and boosts ok no eml's im quite sure my maf is a little on the way out though...

I was thinking it could be maf related or maybe coilpack or possible tb out of sync

anyone else got any views on this..???

don't think anyone can give you much on this.
you'll only get opinions really.

get it logged and go from there

may be that when you slightly depressed the throttle it let a lil more fuel or ait in which got unburnt and exploded in the exhaust
