im not blind, it just an expression that i cant drive your car, and use my 6 senses ( no taste) and experience the totality of driving. (cant see you shift either)
There are no lack of things to witness. driving or running the engine.
2 volts. not 7 (so does this 2vdc change if you turn the bleed screw (top rear of TB)?, 2 volt (ill pretend meter works) implies ecu thinks RPM is too high.
but.....
the second video shows the ISC failing, hard. "no regulation" the ECU is not controlling the ISC. rpm drifts by engine loading.... that is wrong... that drift.
"the purpose of the isc it prevent that drift." the ISC servo is the regulation of idle speeds.
but.....
so is the idle switch closed? if yes, the turning the bleeds screw would wake up the ISC and cause it to start regulating.
the idle switch is easy to test in 1min, flat, back probing the idle switch
what was idle speed in video 1? when at 2vdc on idle.
and
The 16v TB idle switch is seen here, pin 1 is bottom pin , pin 4 is top
the switch is. pin 2 (second up from bottom)
connect dmm there, black to engine ground , is ok
then dmm red lead tip. to pin 2, ,the voltage is near 0vdc even , just key on or at idle.

we can only set the dutycycle (bleed) to 7v if the engine is running the ISC, regulating, it is not regulating in video 2.
we must find out why?
