ok its a M/t I missed that. and your maf was weak
why not clean it?
all mafs get dirty from eating nasty fumes and dirt from car in front of you. all do. and the MAF on G16bs function at IDLE TO. (unlike other cars)
clean it with MAF spray, every 50k miles, its a service point to do , not in any factory book,.
a weak maf causes low fueling rates, if bad enough it can stall due to lean burn stall.
the ECu scan data will tall you if the maf is weak, see my maf graphic plots, on my MAF page.
d the car is not stalling anymore. But it is idling at 560 rpm. (i missed this post sorry)
no do not mess with that black cap TB screw,
this i duty cycle settings. Unless someone else messed i tup.
here are the screws.
Throttle VAlve TV.
1: TV stop screw never touch it, if the TV fly-plate is near .0005 (3zeros count em) inches, then this screw is not molested. leave it alone... is best.
2: the black cap duty screw on the top of TB>
this is duty adj.
duty cycle puts the ISC in the center of is range, (command authority)The ecu then can raise RPM +400 rpm or -400 rpm (crude unpublished spec. and depends on engine pumping losses,etc)
If at 560, on the OBD2 scanner, is it here too, ? seams yes, with 60 digits, not seen on dash.
you then check duty with a dUty meter.
i check across the 2 ISC wire pins, for 200hz, square wave that is perfectly in symmetry. with a scope or my FLuke meter that has DUTY mode.
if the duty is 50% at hot idle, then ok
if not change, it to 50 with that screw.
that is it.
btw 560 is ILLEGAL RPM , the ECU controls HOT RPM, when you see 560 that means, the ECU JUST LOST CONTROL OF THE ISC< that is all it means, why is more testing
the isc, i clean it and for 1sec, duration max. hit it with 12vdc across its pins.
to see if it clicks and opens 1/4"
default is closed, 12vdc is open
it draws 1amp current so do not leave it connected to a battery or 12vdc supply pack.
it will get hot and damage it, so just pulse it fast by touching leads like my video show.s

this is ALL IT DOES, no magic just a solenoid air valve with spring.
