hi,
I have a 260z with a 280 engine with twin hitachis from a 240Z and whilst using the car today after a hot run the idle seemed a little low and eventually stalled. When the car had cooled down it was ok again. It seems fine running the engine up to temp with the hood open so was thinking it may be a fuel vapourisation thing with the hot weather etc. I have the correct heat shield under the carbs too. When I blip the throttle when hot and at idle it’s fine and revs cleanly through.
I recently fitted a viscous fan to accompany the electric fan I have and I’m thinking the fan is pulling in additional heat from the rad into the engine bay which is causing the issue
Has anyone else experienced this and what have people done to prevent this from reoccurring?
Your thoughts are most welcome
Thanks, luke
