fuel injection below a certain manifold
pressure but
if you set the threshold too high, it will cause continuous misfiring when you lift off the throttle.
Other than the rough idle and hard starting there's no problem, the engine has plenty of power at high rpms and doesn't seem to be misfiring, both of which I think it would have problems with
if the

fuel pump, filter, or
Fuel Pressure Regulator (F
Fuel Pressure Regulator (FPR).
Normally it needs to be check with
pressure indicator but still you can check

fuel pressure regulator or
fuel pump.
In order to isolate the hard engine start the first test will need to be a
fuel pressure and leak down test to see
if the
pressure is within specifications when the key is turned on and the
pressure stays up when the key is turned off.
Check the
fuel pressure and replace the
fuel filter first to see
if it helps.
