Hi guys,
Recently during the mornings when I start up my skyline it seems to shudder a little. The oil pressure remains at 0 for a few seconds and rises as soon as the shuddering stops. When I bought the car it didn't have this problem. Also this only happens when the car is first started, subsequent ignitions don't have this problem. Any ideas as to why this occurs??
Thanks in advance.
EDIT: I forgot to add that the car is completely stock, no mods whatsoever.
