on a carby you would measure the fuel pressure before the carbys on the fuel line, however carby engines react differently to fuel pressure problems. so this thread dosnt really apply to carb.
EFI is your fuel pressure is fluctuating, your engine will suffer from this.
if your fuel presure is constatnt and within specs, then you should start to look at your injecotrs or posibly even your ignition system.

to add....if perhaps i was to take out my injectors- and get them all pulse cleaned ( ir whatever its called at a workshop) woudl this rectify the problem ? ATLEAST find out if its the injectors clogging up etc ? ( this is on a 13 year odl car...with the same old injectors...)
my honda civic has a similar problem - the less fuel in the car the crappier the car runs ( less smooth) ? And , the fuel gauge is VERY unreliable- goes up and down all over the place.
Is this due to a fuel pump problem , John ? Or somewhere is there a blockage or ?
