the ported vacuuum on the top of the throttle body should be dead hot idle. is yours.
the ecu cuts the EGR 2 ways, one with ported vacuum and the VSV, the VSV drops vacuum at wide open throttle, something then ported vacuum can not do.
i think this is how it works.
no, im calling your test a 1993 test, you make it work like a zero MPH 1993 car. your parked tires on ground and the EGR is live, gunned. see?
you test is great. and very simple and i just added to my page, egr gen2a.html
keep in mind a new or really GOOD strong CAT can in fact hide a horridly running engine, this is its 2nd job. passing smog, means very little in fact.
you car has 3 way cat, one of the 3 ways it , the EATS all NOX it can get. way.
see?
if you want the cat to last long, (they are like $1500 at suzuki) a good running engine does that,
the less crap you send to the cat , the longer it lives. (crap, = NOX, HC, and CO)
im pretty sure the code 51s never lie, (sensor no packed in carbon , for sure)
low flow or no flow. is code 51.
the flow needs to be full. so the CAT can last for ever.
the stock cat is way stronger than new cats.
they found a way to give you less, (magic rare earth materials) and still pass the 8 year rule. (dirt dogs they are) The stock CAT is a very high quality product.

are you saying the TB nipple has vacuum , at hot idle>?
