the filter on the g16/a/b both have a banjo bolt. and a 6mm threaded, iSO screw sizes. that fits special hose,, the $19 harbor freight kit has this hose

sure glad to see perfect spark plug,...

readiness monitors
speed up
the 2 hard ones
are
Drive fast say 45-50 mph, light flat ground, easy cruise, test A clears, then take say and off ramp and lite car coast to stop in gear, test be clears.
EGR clears.
then the pest, EVAP, will not clear until tank is 1/4 to 1/2 empty, and can take 1/2 hr driving, depends on if Evap 1,,2 level, those years.


if idle drops, now hot, I say, turn bleed out 1 turn (top rear of TB)
I think its not misfiring
and fuel pressure is ok
engine ok
The duty cycle setting is pain, if lucky we can use DMM on the ISC wires. late

spark is easy
1;hot engine ,800rpm
2: connect mag coupling to front #1 HV wire
INSERT PAPER CLIP TO (UNBENT) TO FREEZE PINS, DLC JACK.
3: point gun at top of crank pulley
4: PULL TRIGGER, SEE STROBE FLASH.
5:SEE IT LAND 5DEG LEFT ON SCALE. my guess ,its dead on..... if way off tell me,, id not worry 1 degr..

THE FREEZE JUMPER , PREVENTS rapid advance bouncing (normal at idle)
my horsed up

recap.
the tps switch must be closed at every time right foot leaves, gas pedal. o
or idle goes wild. (wonky)
i bet fuel pressure is prefect
i dont bet idle switch is calibrated.
i bet duty cycle is off (ISC calibration is what this means)


did you say 02 monitor,not complete. front or rear?
front should be fast. like down street fast the rear will not run until front works perfect.rear is cat test. and that times time too.

i thing lots of the important things are A-OKAY


good night and happy trails.
