1994 Sidekick 16v AT 4x4 4dr virgin ECM Ruby's still there

so yours is near 5Ms and not 2. that is very bad, if true.
5MS is ECU output and if is near there hot idle then you have bad engine sensor readings or bad ECU. (id say sensors)
not bad injector they only do as they are told. (signals)
one other thing is the tech1 does it subtract,  1ms from PW to show true injection rate?  seem it should to me.  my guess is not.
so 4.8mS is really 3.8mS true injection time. and is 120% too high.

here is my attempt. min open time is dead time (inertia)

my best  try.  if true , your  ECU is injecting crazy high fuel, not just rich.  270% or 2.7 times too much fuel,  the sensors read wrong.
1.8x 2.7 = 4.86ms
assume tech one is not fibbing, and is on ECT we do not know if tech1 sees real Injector PW or uses a table based on ECT readings and maf.(IDK)
this is why real scopes are a winner (no lies) and can see the true dead time and true injection rates, no lies.


now TBI (one Injector G16) my real scope is drew this, for better way to comment on PWM.
see 1.4Ms here. hot idle,
0.7mS dead time (inertia of pintle)
see the modulation it does to not overhear the tiny coil.
that is no load Acceleration not in gear, and no hills.  just hand gunned throttle.
dead time is when injector can not inject fuel at all. (from 0v to 12vdc time zero) fuel flows at the first left small "c"
