156 2.5 v6 idling stutter?
I've just had a auxiliary belt disintegrate on me and fitted replacement with tensioners and pulleys. After some tinkering and getting the belt fitted correctly the natural progression was obviously to start it up.
It sat at idle for a while, whilst the new belt bedded onto the pulleys.
Heres the problem, when its sat at idle theres a judder almost like theres a mis-fire, however get it up to 1500-2k rpm the engine's as sweet as a nut?
All guages work as they should, there appears to be no fluid problems and its got plenty of oil in it!
Can anyone shed some light on it? I've been told it may be a head gasket failure (without the obvious signs), overheated spark plugs? Any help would be appreciated.
