MOST TIMES THE Q AND P CAP BACKWARDS IS OK.
the test to see that, is look down the pipe, inside , if its straight pipe, its ok, if not now. there are many of these modulators, on toyota's with tiny venturi on one end, omg, P and Q matters.
Mind your pints and quarts? LOL
yes, 93, but its the ECU that matters, the exact year, and on sammi, not sure what is there. sorry.
but i bet this EGR opens, HOT, parked, in neutral gunnning the engine, did it?
do the live test next. do not get it smog checked until the live test passing in your garage. driveway, or ? at home.
but the rule is 93.
no need to lift a tire.
engine hot.
idle switch works, right. (im sure it does now)
gun throttle by hand but not wot. just do like 1/2 throttle guns over and over.
person to with stick hand mirror looks at the EGR main diaphragm and see it move in 1/4 inch, to get full stroke, do aggressive gunning.
what happens is exhaust back pressure moves that diaphragm. on EGR main, as does the MOD diaphragm unseen.
the mod valve works like this.

if you get good strong putts, the mod opens more.
and P and Q vacuum is strong to the egr main, and it moves next.
I hope that trail tuff harness wires the EGR VSV right.. oops..... it must.... be wires 2 wires to ECU or EGR will be dead.
that is way doing the vacuum tests first. finds this first. working the correct ends first. and that starts at the VSV (and the TB vacuum port)
rock on!
