ok, if im doing say 40 and above in 4th or 5th i can take my foot off the accelerator and press the clutch, in doing this a car would normally coast and tickover at idle revs, mine doesnt, it looses all revs and cuts out like a stall. Same thing happens say if im going down a motorway sliproad and going down the box to slow down (5th to 4th) if i take too long changing gear so that the revs go towardsw what the car should idle at it cuts out again, it starts up ok by just letting the clutch out in gear while im moving. Anyone know whats up???? Can get it to repeat this problem time and time again but it wont cut out in 1st 2nd or 3rd at low speed.
Anyone ??????

Cheers.
