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
