P0420 code. SR20DE 01 Sentra
well i was searching different forums and read that the code was common but all the threads i read were 1.8s or QR engines . common fix was a O2 spacer fix. you've seen me posting threads about me needing a new manifold but was wondering maybe doing this trick will fix things , also all of a sudden my CEL light turned off by itself , didn't actually notice when it had done so. i told my mechanic to just leave it on and not to reset it btw ... if i go get the car smogged will it pass? when he ran a test the OBD meter said it would .
need a little more info on the spacer fix , says i need to gut the manifold? if i do that i wont be able to return it for core if i acutally do need a new manifold. want to hear some opinions . just get a new manifold ? or try this trick? not sure when was the last time the mani. was replaced , the engine is rebuilt btw.
