Cali smog,

[Thethrash]

Hey guys so i have been trying to smog my 91 240 (dohc)
it passed everything except the nox(common thing with 240s)
so i cleaned the egr valve and the metal pipe that goes around form the exhaust manifold to the air manifold.
My nox was reading 3300. and i was wondering if that's possible, perhaps i hooked the egr back on wrong?
can some one please help me :/

just bypass the egr and run it to intake vacuum. there's threads on here or on the web on how to do it.

Mine failed 9 times, lulz. If you have money buy a Magnaflow cat. It helped me out a lot.

What were your nox readings? I might have to do that next time smog rolls around
