hi,nearly every morning especially when cold,i turn the key to start engine,once engine fires up, the first 3 or 4 seconds of idle seems to stuggle a little,then the revs pick up and all is well.its had recent plugs.car is a v4 1998 sti type r,completely standard with 77k.
i dont think its anything to be too concerned about but my old uk turbo wagon never seemed to do it.
any ideas?

thanks.

 

Maf? I think these are quite troublesome on the classics and often needs replacing?

 

unlikely,the v5-6 is normally the one for fragile maf,i have v4.

 

bit strange,but since i posted this thread it hasnt done it lol.
