![]() 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 :/ |
