my '89 E30 has been purring along beautifully.
last nite, i went for a short spin. on return, just befor turning off the engine, it started to idle noticably roughly.
this morning, i started the car, it was idling VERY rough. i also noticed that i was getting blue smoke out the exhaust.
nothing on the diagnostic computer ...
i checked hoses, nothing obvious.
fuel, ok. oil, ok.
fuel pressure (have a gauge mounted) at the pressure regulator, good and normal.
start again. even rougher, can't rev up ... and serious surging down to < 100 rpm has started. stop.
deciding to take the car for a spin around the block, i start again, get 20 yards, and the car stalls.
now, it won't start at all. electronics seems all ok; crank sounds healthy.
just no start.
i've never dealt with such an immediate/rapid failure.
can anyone suggest what the problem may be, or where/how to start looking?
