Vaccuum tested BPT also and no pressure at all. I watched him test, he was pretty cool. He said if it was a bad CAT then all the readings would be fairly high across board (all would be effected)
I guess id need to clean the intake runners as well?
I had car running hot also (drove around for hours)
I am down to half a tank and that "guaranteed pass" bottle stated to run tank empty and then put gas in then SMOG test. But Ive been driving all over town and just need to SMOG to sell to a buyer like 4 days ago........F'ng A MAN
NOt "Gross Polluter" on one now, progress? just a 'fail' now ugh.....
INput greatly appreciated........

Honestly I don't know what a bpt is, but if it's the egr, take whatever you need to off, and clean it by hand.

The test pass stuff, like seafoam, can't really reach the egr, because it's already burnt by that time. Don't waste your time and gas driving through the rest of the tank.

It still says tampered....?

yeah, Im not sure why, these jerks in koreatown are creepin in deep! lights by the firewall. Caught, 1 of 4 tiny hoses under throttle body disconnected and were like "HOLY CRAP". so maybe i should go elsewhere later. the Egr is directly connected to the BPT *EGR backpressure transducer*
guy vaccuum tested and said it should have pressure/vaccuum, no vaccuum, no EGR working to pull emissions(evaporated gases) back through the system=high nox is what im getting.
EGR is cleanable i read, but the BPT is one of those 'replace only' POS!
so,if I get a new BPT its about $60,im going to be at $170 ;after three failed smog,resmog,smog sessions.
I couldve got a 'hookup' instapass smog for $200ish.,....but i
