Wondering if someone can help me, I'm having a couple of problems with my 1994 F78.
For about a week or so now, every time I turn the engine off the fuel seems to drain out of the engine, and needs about 6 pumps on the primer before I can start the engine as normal (within two turns of the starter).
Then recently I seem to be having another, perhaps related problem, which is that the idle speed varies erratically, from normal to stall. Today I was sitting in traffic after a motorway run and it almost stalled. I turned up the idle speed to 900RPM yet it still varied erratically from 900 RPM to 400 RPM and would have stalled had I not kept touching the accelerator every two seconds when the engine was at idle.
Under power the car seems to run OK, although just before it started wanting to stall I did notice a loss of power under acceleration from the lights, but after that even though it wanted to stall at idle it seemed to behave as normal under load in town traffic.
So does anyone have any ideas what could be causing these two strange problems? Any chance it's related to the recent cold weather?
Any advice would be much appreciated.
