right then my brothers mk5 rs2000 when warm runs bit rough, feels like something to do with plugs. bit of hesitation, got new plugs and 2new coils on, but when it warms up it still does it

i drove it earlier it warmed up etc, turned it off tried starting it again and it wouldnt start was just turning over, asked a mate, he said could be temrature switch, as is giveing it to much fuel etc.

so need to know what one im ordering etc, is there only one temp switch? and where is it located?? pics would be good cheers all

anything else to try to cure this??

cheers lew
