ok here is my problem
Failed emission

real hi NOx 2354 instead of limit 1167

check EGR actually I bought a brand new one from Toyota $154

i did the vaccum test pass

I started the car with the EGR valve removed to see if the exhuast port for egr is clog its not

clean lil pipe from the EGR valve to the intake thats fine

put everything together

try sucking on the vaccum line going to the EGR while the car is at idle

it doesnt do anything, no stall no studder nothing

so went through emission again with new valve only brought it down by 54 points


what should i do New working EGR just dont work on the car

thank you for your time guys









even check the lil VSV solenoid for EGR valve
