Really I have had a few fuel injected cars do this. The last - a granada
became all but undrivable.
It started OK but after 2 mins it began...
It was a multiplug down the drivers side of the engine in this case, it
looked dry, and wd40 didnt do any good either. Left apart overnight, with a
fan heater on low, blowing on it sorted it though. Rain can be enough.
Sensors or EMS systems seldom go intermittent. HT leads can but they do it
worst under load.
Does the fuel pump give constant pressure? it could be failing intermitently
