yes EGR is complex on these years. 89-98.
in latter years ( or all J10 or J20 engines up)
they ended the VAC MAGIC EGR HORRORS. 1999+
they run the mAIN with an electric motor, and no other parts at all. with just 1 part. (main)
this one part , is controlled by the PCM (ECU) the ECU now does engine load calculations fully. and runs the EGR motor as need be all pure magic of software(firmware)

[url=https://fixkick.com/sensors/EGR/90-95/SLIDE/html/image_7.html]here is the ported vacuum port EGR as you can see it is blocked at idle this ends all EGR actions at idle for sure, then VSV does same , is closed at idle, and WOT.
I forget i had so many photos of EGR bits.
the idles to high failure, (not you) but is caused by this?
ah the moving rule to test EGR 100 % parked is not easy, here are the FSM words, (for those dohttps://fixkick.com/sensors/EGR/90-95/SL...ge_13.htmling smog checks this is how,before that doing this first, not last)
omg I even have this beauty on my EGR pages. check this out , this is the mono port, late 1995 and to 1998 G16b
the hole on the left barks hard, #4 exahust full pressure against the CAT BRICK , up to 2PSI in fact.
the hole on the right is under hard plenum vacuum at all times at idle and at up to 2 psi exhaust flow if moving, only hot engine.
The 3 gaskets MUST NOT BE MISSING OR THIS FAILS HARD.
This is also called the CALIFORNIA intake manifold 1995.5. and is the best, and used until 1998. we can even install this on 1992 engine and works, better. kicking quad ports to the crub is great trick. (EGR on G16 here are complex,) the CAT must be good or all this fails. that is how EGR works here and same deal on 95 Toyota's too. it's not rare its OLD TECH.
